Have you ever used OpenSCAD, great, isn't it? Now, imagine that you are not anymore limited by the OpenSCAD syntax and libraries. Imagine using recursion to create objects, inheriting some parts from others, having at your disposal hundreds of geometry libraries, and much more… that's the OOML. The OOML is simply a C++ empowered OpenSCAD.

OOML stands for Object Oriented Mechanics Library. The OOML is a set of tools written in C++ that allow designers to create mechanical parts using the C++ language.

OOML applies the model of Object Oriented Programming to Mechanical Designs. Parts can be inherited from others. A part can join together other existing parts, and so forth.

OOML has up to now no external dependency and can be used in any computer having a standard C++ compiler.

Up to current version OOML generates OpenSCAD code. Using OpenSCAD designers may generate the STL of the parts.

OOML is Open Source, you can use it, modify it, share it.

OOML brings together both the design of pieces through code (as it's done with OpenSCAD) with the programming power of an Object Oriented Language as C++.

OOML provides a powerful tool for designers to boost their creativity building mechanical parts. As it uses C++, designers may use any other existing C++ library to calculate, manipulate, create their parts.

OOML allow designers to create and share their own Parts Libraries, which will certainly enrich the community.

In order to improve the tool OOML (http://iearobotics.com/oomlwiki/doku.php), we built this motorboat from libraries OOML whose they are written in C++. The MOTORBOAT is developed from zero and it is not based on any model previously developed by other programmers. We only use the code .SCAD of a propeller, to build our propeller (http://www.thingiverse.com/thing:8688 ).

Here is a video of the MOTORBOAT (in spanish):
Pulleys:
youtu.be/dUqTDfMHCe8
Gears:
youtu.be/C185LOEoUI0

Test in water:
youtu.be/0xFm2y-97Ts

All code is written by QtCreator program, this program can work in parallel with OpenScan program order to view the process of developing of the different parts.

The MOTORBOAT was divided into three parts. The first part is the physical structure of the MOTORBOAT and is intended to float on water. The second part is based on mechanical system pulleys and belt and is intended to transmit power to the propeller. The third part is based on other mechanical system gears and also aims to transmit power to the propeller.

The gear code has been parameterized to function as a new library OOML.

To supply power to the mechanical system we used a motor DC that is activated or deactivated through a switch.

Finally, the attached codes are. "STL" files. It also includes a ".RAR" file which includes all the generated files (."CPP", ."SCAD", ."STL").

Additional things.
To assemble the physical structure of the motorboat, we need:
Waterproof adhesive.
2 flange to hold the motor.
To assemble the mechanical system based on pulleys and belts, we need:
2 M3x10mm screws.
10 M3 washer.
2 M3 nuts.
1 square section belt 80Øx2.2mm.
To assemble the mechanical system based on gears, we need:
2 M3x10mm screws.
2 M3x20mm screws.
2 M3 nuts.
14 M3 washer.

This project consists of placing a propulsion system for a robot by means of a DC motor and a propeller.
It consists of three parts:
Propeller of four wings that will be linked to the motor shaft.
Protective casing of the propeller for greater security, together with the support of the motor.
Support that will serve to replace the motor DC and unite the propeller with its case to the robot.
All the measures can be configured so they can adapt to the necessities of each project.

Minimalistic 52mm lens cap holder attached to the thin part of the camera strap.

The print shown in the picture was done on an eMaker Huxley with supply3Dpla.com black PLA using 0.3mm layers. Shot with Olympus E-P1/Canon FD F1.4 50mm lens, also the combination i made the cap holder for.

This is a card holder for settlers of catan gamecards, 54x80mm
Keeps the cards from going all over the place.

Latest update:
Added a nice Logo in the cardholder.

Version 4 now with the patented "I just take that last card"-cut :)

Now there is also an OpenSCAD file. It is made with the same dimentions as the previous blender project.

Also avaible on github: github.com/condac/gamecardholder

I sometimes need an impromptu diffuser to use with the built-in flash of my SLR camera.

This small clip is installed *after* the built-in flash has been deployed, and provides support for a standard business card to be inserted white side up. The flash is thus bounced from the ceiling and lessens the harshness of the flash, e.g. for portraits.

Thanks to TheCase for the original Nikon hotshoe cover model, from which this is derived. I found that the Nikon version had to be scaled by 0.95 to fit the Olympus SLR (E500) hotshoe. May work on other brands of SLR, depending on the configuration of the built-in flash - let me know if it works on your Canon or Nikon!

This moon rover is pretty simple; the real point is the treads. The idea of turning my Stretchy Bracelet into tank tracks is thanks to BenRockhold. Turns out it works really well: if you push this around on a slightly grippy surface like carpet, the tracks roll easily.

In fact, the track keys into the wheels so well, this could probably be used as a timing belt or chain.

Its a replica of the Pirates of the Caribbean Coin. Actually the face of the coin is not in Hi-quality due to the struder precision, but the stl has more details.The diameter is 50 mm. Files included are pirates of the caribbean coin face (potccf) and pirates of the caribbean coin back (potccb).

Mars Exploration Rover:

Wheel with integrated engine and a servo.

In progress.

This is a fully printable mobile robot I designed and built last year. However, it wasn't very useful until Julián Marín Mato added some electronics and wrote some code to control it with a gamepad. Now that we can say it's finally 100% functional, we'd love you to play around with one too!

To see it in action, check out this video: youtube.com/watch?v=54MXA22bOmQ

There are, of course, things to be improved: using more powerful servos, strengthening some parts, adding wireless comms, etc. All that will come in the (near?) future.

At my university we have a Makerbot Thing-O-Matic which has been aptly named "Madre" ("Mother", in spanish) because it will print the necessary parts to build a second generation of 3D printers (several Prusa-Mendel printers).

I decided to create a small sign that we could place on the printer. I printed the letters separately from the background, in different colors. The background has the shape of the letters indented so that they can be fitted inside. I was amazed by how well it turned out, but obviously few people (if any) can benefit from the files to print this specific sign, so I have written a tutorial explaining how to make your own design using Inkscape and Openscad.

mrgroup.dyndns.org/mrgroup/doku.php?id=3dprinting:home

I hope you find it useful!

This is one more element that used a big "vitamin" (non printed part)in my reprap that i wanted to replace.
The squashed frog is the part that is underneath the Y axis platform, and to which the belt as well as the bushings/bearings rolling on the rails are attached.

The initial version was cut manually from plexiglass, but due to my lack of good quality tools/workspace, while it worked , it certainly would not have won prizes for quality !

So i decided to design a printable version, that had to :
*be mechanically resistant enough
*be relatively fast to print
*be made of more than one part since it needed to be as big if not bigger than the maximum print size
*have mounting point for the bushings as well as the belt clamps

So this is the solution i came up with:
*it is made of 3 parts , two of which are identical
*it requires 4 nuts and bolts to be assembled
*the inner holes with roundings enable the parts to be strong yet not use too much plastic
*it is relatively fast to build and easy to assemble
*it works well !

I have yet to test it with a heated build platform but i am not too worried, because if the printed bushings of people using a hbp don't melt, then there is no reason for this to melt :)

Very important : it uses the great bolted pla bushings by Griffin Nicoll available here : thingiverse.com/thing:7157

When I saw thingiverse.com/thing:9383 by PacManFan I remembered that I also was playing a little bit with lead screws, auges, whatever but "I forgot" to upload it...

It has been hard to find back most of the parts I was printing and using to do those tests and it has been really hard to find the OpenSCAD file that I upload here. I have hundreds of them.

I've choose this OpenSCAD because is the most complete one and the one that is less hardcoded (but still quite a shame). I've put some effort to clean it here and there but still there's no warranty at all that it will work fine.

No warranty neither that the stl provided will fit properly, I think that they should but... who knows????

This time I don't have extra pictures to show (my pleasure), instead I have this video... youtube.com/watch?v=a-4naMl-TOQ

I just hooked up the motors to bot1334 and ask it to build one stl via RepG.

The lead screw provided has a travel per turn of 36mm and I was not modifying the machines.xml to adjust to real sizes.

I got some sheets of sandpaper 230mmx280mm (a little wider and shorter than A4) and wanted a handy holder to turn strips of it into sanding blocks to make jobs easier. This is what I came up with.

It is designed to grip sheets of sandpaper cut to 40mm wide by just over 200mm long, but with the files included it should be easy to re-design to your needs.

It's a turnkey of the Formula Student Team Escudería UC3M.

I apologize, it is not parametrizable, because it difficult shape

This is the parameterized version of the servo wheel. The wheel diameter, height and o-rings parameters can be defined by the user. These are the type of wheels we are using for our printable robot projects. For example, the Miniskybot robot ( thingiverse.com/thing:7989 )

Currently the target servo is Futaba 3003.

YAPML yet another poor man's library that makes things finding it hard to render and taking its time to compile.

In this case the self-replicating polyhedron is intended to give a mechanical touch to your freshly (or not) designed cylindrical surfaces. Hmmmm... you can also thing that those things all-around the cylinder are diamonds and use it for jewelry.

For hanging on a Louvre hook panel, or simply stacking up in a pile, to sort all your nuts and bolts, bits and bobs, odds and ends in.

I don't currently have access to such a panel, so the clip on this tub is a generous estimation, and there is a matching hook that can be easily stuck all over a scrap bit of plywood by using some countersunk screws, to turn it into such a panel.
If anyone does have access to one and would like to share some dimensions for the hooks on them, then I could redesign this for a better fit.

The current design is only two parts for simplicity's sake, and on its side to keep stress in-plane and remove overhangs, but I might consider making one in more flat parts.
Suggest some alternate sizes and I'll make them, otherwise go fiddle around with the IGES part files.

Just a quick mash-up to allow the bins to be joined in multiples without a side panel. There are two versions, one with the notches removed from the original part and one with the side panel added under the original part. The second one should play well with the original bins (i.e. line up for stacking)

This is the 5th version of my printable linear rail, I've gotten everything to finally work correctly. This can be used as a drop in replacement for a 3d printer's X or Y axis. It's rail system is designed to connect together to form any needed length.

This machine hopefully will be my entry for the Gada prize.


Update 06/16/2011:
I worked out a few modifications to the shuttle. Now the lower half of the shuttle can be printed as well, this removes:
4x 5/16(8mm) nuts
2x 5/16(8mm) bolts
2x 5/16 washers

-The next to go is going to be replacing the front 5/16(8mm) hardware with all printed parts. I'm trying to pare this down just the motor and the printed parts.

-I also redesigned the Large helical gear to incorporate the 608 bearing embedded inside of it. think this is an advantage of trying to use 2 bearings in the pillow block. The large helical gear is also now held in place by a printed 8mm bolt 40mm long. This removes one additional piece of hardware.

-The shuttle top now has 4 mounting holes, although I'm just securing the motor with 2 at this point.

-I printed 2 new 3-segment rails, redesigned lower half of shuttle to be printed.
-I also added 2 new pics of the x/y gantry system and uploaded all new parts - I should have another video.

Update 04/30/2013
It's been brought to my attention that the rack file was missing from this. I have uploaded both the rack stl and scad file. Enjoy!

Full writeup on my blog at: eclecti.cc/hardware/physical-keygen-duplicating-house-keys-on-a-3d-printer

It occurred to me recently that I had printed almost nothing actually useful on my RepRap 3D printer, aside from parts to improve on or build more RepRaps. I am rectifying that with this project. The goal here is to generate working house keys by inputing the key code of the lock into a parametric OpenSCAD model. Instead of having to explain to my landlord how I ended up with a wedge of plastic jammed in my front door, I ordered a box of (well) used locks and latches from eBay to experiment on. Luckily, the lot includes both Kwikset KW1 and Schlage SC1 locks, which are the two most commonly found in the US. I created an SC1 model to start with, but I’ll probably make a KW1 soon.

EDIT: I uploaded a KW1 model as well.

Designing the key model was actually pretty straightforward. I measured a key with a ruler and calipers and created an approximate model of it that is reasonably easy to print. I then got pin depth specifications and parametrically differenced them out of the model. To generate new keys, you can just edit the last line of the file and enter in the key code for your key. If the code isn’t written on the key, you can measure the height of each bit and compare to the numbers in the Root Depth column on the aforementioned pin depth site. Perhaps more nefariously, you could implement something like SNEAKEY to generate key codes without physically measuring the key.

(This thing got featured in the thingiverse blog: blog.thingiverse.com/2011/05/30/this/ )

When my daughter saw this thing ( thingiverse.com/thing:8859 ) she wanted to take the pieces off to have the "X" and "O" to play with for Tic-Tac-Toe. Since I had been messing with a case ( thingiverse.com/thing:8860 ), I decided to try to mash them together into a little travel Tic-Tac-Toe game.

Drafont is a font system for the OpenSCAD program to have Unicode characters from scalable TrueType fonts.

Example Usage:

To make the Hi! greeting at left, do as follows:

1. Download freeserif_basiclatin.scad and freeserif_cherokee.scad (see below for download links)
2. Type this into Openscad:

use <freeserif_basiclatin.scad>;
use <freeserif_cherokee.scad>;

d=12; // detail level - use 1 or 12
freeserif_H(d)
freeserif_i(d);

translate([-800,-1600,0])
freeserif_13a3(d)
freeserif_13cf(d)
freeserif_13f2(d);

Features

1. Each character is a module. Chain them together for auto-positioning
2. Each character can be referred to by unicode, or a 'shorthand' name
3. At the top of each .scad file is a list of the characters available
4. Two detail levels: 1 and 12
5. You can generate your own .scad font from a Truetype font, with any detail level you want. Download the .py files, edit settings at the end of ddump.py, and run it as follows:

python ddump.py FreeSerif.ttf 0x0041-0x007a > freeserif_basiclatin.scad
python ddump.py FreeSerif.ttf 0x13a0-0x13f4 > freeserif_cherokee.scad

Bugs

1. If you use the same char twice in a word, you have to use two _ (underscore)
2. Some complicated characters won't render properly
3. It is slow
4. CJK characters in FreeSerif not working
5. Some fonts don't work, at all (Sawasdee)

Here's a more polished, production-ready update to the domekit 3d-printable geodesic connector system. We refactored the central hub to feature a rounded edge and use less material. The strutcaps are shorter while being more durable, and include an integrated thumbscrew (with captive nut) that locks the strut to the node. This makes the structure easier to assemble, because you're not trying to snap the balls into the sockets — just slide the strut into the shaft and turn the screw.

please visit domekit.cc for more details

I made this specifically because my brother wanted something that wasn't easily molded with an injection molding machine. The undercuts on the bollards and the jack port should make it impossible, if not unrealistically expensive to make that way.

The picture is pretty self explanatory. Put earbuds in, wind and then push the jack end into the hole provided.



EDIT: This only seems to work with the new iPod / iphone earbuds with the volume control buttons on the cord. Thanks to all those who tried with other earbuds.

Title is self-explanatory...

It holds a spool of solder and has a little slot for directing the solder as you use it. It's really just a rough test that I did whilst playing with Tinkercad.com

I might tweak this further too, so I'm labeling it a work in progress.

With the recent flurry of screw-related things I decided I should upload this before it was too late. As Syvwlch said, publish or perish! This is a screw-based connector system intended for use with a modular robotics project. The parts were originally designed in Alibre. The raw Alibre files are pretty hacked-up, so uploading stl-only for now. Of course, an OpenSCAD version of these parts would be fun also, but that will have to wait.
