You got gears in my weighted storage cube! You got weighted storage in my cube gears!

This Thing is a mashup of:
•Cube Gears by emmett - thingiverse.com/thing:6073
•Weighted Storage Cube (from Portal) by cyrozap - thingiverse.com/thing:1614

a nozzle and a cap for a tire inflator with gauge.
since i removed the gauge for another project, and i needed a blowgun i designed a cap and a nozzle.

This is a stand to display a Rubik's cube on a desk or shelf

A case for the reprap.org/wiki/RAMPS1.3 board. Used here to drive a small milling machine with pyCAM/FiveD/ReplicatorG toolpath.
It is a tight fit that does not leave much room for ventilation so take care that the drivers do not run too hot.

The evil purple tentacle from Day of the Tentacle! He wanted to rule the world, now he can rule your desk... :)
All of you, who don't know him should play the game, as imho it is one of the best adventures out there. besides monkey island ;)

Reprap Branded Double helix

Can be printed without support, if your bridges are up to the challenge.

Included Solidworks source files.

Shower head holder that can be clipped onto a rail.

There's also a variant for wall mount: thingiverse.com/thing:10407

I found this on Google 3D Warehouse Futurama Planet Express Ship uploaded by: Admiral Zack

sketchup.google.com/3dwarehouse/details?mid=761acea752546ee92e6b803d08c94bc8&prevstart=0

I cleaned it up some in Sketchup (swapped surface directions) and exported the STL file.

I know there is already a flyswatter here ( thingiverse.com/thing:9518 )
It's a little prettier than this but I was interested in making a parametric one so that it was adjustable.

So, here it is.

You can adjust the size, thickness, hole size and spacing and the size of the stick.

7/8/11 Uploaded thinner version (1.25 mm)

A (semi-parametric) tie holder.
I redid the design in openscad, so it's semi customizable now.

The design as laid out is for a 8mm diameter rod; the hook itself has a 10mm diameter, which lets it slide easily but doesn't let it unhook without force.

After playing with both the Heart Gears thingiverse.com/thing:6291 and Gear Gears thingiverse.com/thing:6533, a good friend wanted something different. She liked the way the Heart Gears moved and is totally into solar power, so she asked if I could make gears that looked like a sun. Believe it or not, I am very new at this and had very little experience with OpenSCAD. I understood that if I could get an stl file of a sun it should be relatively straightforward. Unfortunately, I could not find a good one. However, I did find the Geek Campfire thing by jonschwartz thingiverse.com/thing:578, and thought it would look pretty cool if I put several of them around a squashed sphere. Voila! I made her one in translucent blue PLA (at her request) and now you can make one too. The image of the one I printed is an earlier revision (hence the flat ends of the two tallest gears), but I fixed that in this release. I have included an stl of the complete assembly, but only so you can see what it looks like.

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 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.

There is a little video of it building here:
youtube.com/watch?v=nRKHwylv1Ms

This is an original work, but is similar to:
thingiverse.com/thing:7614
thingiverse.com/thing:8881

The 1.0 version of the Bezier library included a simple linear extrusion of the bezier surface. The things this derives from added a quick and easy 'shell extrusion', which took into account the normals on the quads to create true 'inner' and 'outer' quads.

This thing makes a few improvements to both the normal calculations, and rearranges the libraries slightly to accomodate for future curved surface/solid things.

As a bonus, the hermite.scad file is thrown in. At the moment, it only has basic Hermite calculations. It even has a surface thing. So, if you want to play with that, here it is.

Also, in terms of library function naming, I've switched to being more explicit and rational.

linear_extrude_bezier - extrusion in the z-axis
shell_extrude_bezier - extrusion along the normals

So, for Hermite, it would be linear_extrude_hermite, shell_extrude_hermite

One of the cool features is the ability to show the normals, per vertex. This is extremely handy for debugging purposes. This, combined with being able to show the control mesh, makes for some nice visualization. I was actually able to spot a bug in my derivatives calculations by looking at which way a couple of normals were pointing.

Also, I've combined the bezier functions into the maths.scad library, so there is just one fewer files to download.

UPDATE: One more change I forgot to mention. I introduced the terms 'berp' and 'berpm'. Bezier Interpolation (berp - formerly PtOnBez). Bezier Interpolation of Mesh (berpm). I thought they would be fun names, and in line with the classic Linear Interpolation (lerp).

This is the hires-knot by chylld scaled and with manually added support.

I had some trouble printing the original one because i did not want to omit some of the first layers. The main problem was that the overhang parts bent upwards and at some point the nozzle kicked one of the three parts around.
To avoid this i added some parts which hold the overhang parts down.
Using this support parts the knot prints very nice on my TOM with MK6 starting from the first layer.

The support was added using OpenSCAD, so you can modify it if you like.
It might be a bit more support than needed, but with this models i do not need to get nervous while printing them...

*** Note, while the connectors for this should work fine with a second piece from this design, I found they did NOT work with the standard tracks you get from the regular one inch commercial track systems. So I don't suggest creating any of these until I reconfigure. ***

This is meant to work with the popular 1-inch wooden toy trains. It is my first design in OpenSCAD and I intend to cut multiples of these out of 0.5" MDF using a ShopBot.

Having a demanding full time job and two kids, it may take some time before I actually make all of that happen, but in the meantime I figured I'd upload what I had as it may be useful to others trying to make similar tracks.

This is a derivative work of thingiverse.com/thing:4641 and thingiverse.com/thing:4885 .

It is designed to be Makerbot printable.
The idea is to have the roller bearing filled with marbles and have some board with the filament on top of it freely spinning.
For the board you can use cardboard, press board or whatever is lying around. I used some of the wood left from the makerbot assembly.

To increase resistance against tilts and asymmetries in the filement spindle it is desirable to print the parts as large as the build area of the printer allows.

There are two variations of this thing:
(1) marble_bearing_simple.stl: the simple approach with the same grooved ring below and above the marbles. Should print quite fast without problems on any 3d-printer.

(2) lower_part.stl & upper_part.stl: the somewhat advanced version. To avoid the marbles rolling around evrywhere if you touch the spindle they are enclosed in the bearing.

Both of the designs tolerate quite a lot of load on top of them, i wasn't able to destroy them by staying on them - so maybe they are also useful for rotating heavy things like plants, cabinets ... or a makerbot ;-)

Each of the above variation requires in addition up to 12 marbles with 16mm diameter. The scad-file of variation (2) is parametric, so you can tune it for different marble sizes and different radius (e.g. if you have a larger build area).

If you do not have marbles at hand you can also print them using marble.stl . This is a version with some minimal support to avoid the marble rolling around during the print. It might be possible to print them without any support if your printer is well adjusted.

The Starship Enterprise from Star Trek.

I split this into parts to enable printing without support.

[EDIT] for some reason these STL files aren't rendering here but my BFB Axon as well as Solidworks do in fact load them up. I have also started printing some of these parts with no problems.

The Cylon Raider is the standard starfighter used by the Cylons, in the various Battlestar Galactica movies and television series. Cylon raiders are used as the main line of defense for Cylon Basestars.

I split this in two parts to enable printing without support.

UPDATE: Version 0v1 is a bit taller and I worked on the symmetry and cleaned up the base. Enjoy!

I wanted to put a base on "George Hart's 3D Sculptures" hyperboloid ( thingiverse.com/image:40818 ), but I could not get it to render in OpenSCAD.

So I cooked up this one.

It looks a little like this one from MakeALot:

A stamp with the Swedish "Pirate Party" logo.

*It's mirrored so that the logo will be the correct way when stamped.
*I HAVE NOT PRINTED IT OUT, so I don't know how well it works.

The RAMPS electronics box is too big to print on a Makerbot, which is kind of a pain since I managed to print all the other parts on a Makerbot.

But now that is no longer a problem! This set of files was created with the 3D Interlocking Tiles openscad script. The same file could be used to create a box for pretty much anything (like the different versions of RepRap electronics) that is still printable on a printer with a smaller build volume.

I just left the front of the box open due to the number of wires that need to come out of it (4 motors, 6 endstops, thermistors, power, USB, etc).

When I mounted it I just used a couple pieces of aluminum to hold it at one corner of the bot cuz I didn't feel like cutting out a big piece of wood.

I have made me a couple of spindle boxes. To fix the spindle to the swivel plate I have created a center guide, this one fits to a swivel plate with an 55mm center hole.

To stop the filament from doping of the spool, have I made a handful of clips that catches the filament. All the spools are of the same type even though they are from different suppliers, so perhaps there is some sort of standard for those. (DIN 8559)

Not exactly an intellectual challenge, but an interesting print!

I still find it amazing that it's possible to print these vertical columns.

Yes. Thank you, naive human. Now, I can finish taking over the world!

A bolt shaped pencil case

After spending the weekend building and testing my new MK6 extruder, I had seen quite a few of these and needed to exorcize thoughts of them rolling across the floor.

If you don't have an MK6, save up for one - they're fantastic!

Due to my mistrust of my heavily modified Makerbot, and considering some of the experiments I'm planning, I decided I needed a fire extinguisher close at hand. I found a reasonably priced unit in a aerosol can form factor that should work perfectly, but it didn't come with a mounting system...

I think this mount will work for any standard aerosol can i.e. spray paint, spray lube, etc. The clip part is a little loose around the can.

A foot that stops the door. A more long winded explanation would be:

A plastic version of what goes in shoes, cunningly shaped into a wedge such that it may encourage doors to stay put.

Importantly, one side of this is angled and ends up with a lot of ridges when printed. That makes it great for gripping the carpet.
