I've created this little pet monster for the 3D Artist Mag contest with Valentine's day in mind.

Base included, if you'd like to use it.

I don't own a 3d printer so I'm not sure if everything is as it should be.

Now you too can have your own nifty shades. Modeled in blender. *Warning* Will not protect against ultraviolet rays, or muggers.

This is a detailed (though not immensely accurate) model of the Imperial Tie Advanced X1 - Darth Vader's Tie Fighter

It is fully printable, without any nasty overhangs, bridges, etc.

Also, there are alignment pegs for assembling the two halves.

The model shown was printed on a Fablicator
Fablicator.com


I stumbled upon Chanson's detailed Solidworks model over on grabcad, and did some very heavy modification to make it printable, while maintaining as much detail as possible. Original can be found here: grabcad.com/library/darth-vaders-tie-fighter

A small container in the shape of a heart.

Created from a Decorative Garden Mushroom using an Artec 3D Scanner. The model has been checked for holes and given a flat base for printing. This STL was pulled from their gallery of models located at artec3d.com/gallery/3d-models/

This is a terrific print and looks great in Glow-in-the Dark ABS.

This is a simple printable tool for hobbing bolts.


Designed to use (2) R6zz ball bearings from vxb.com to hob a 3/8in bolt

Can also be used to hob 8mm bolts with 608zz bearings with some minor modification, though a small amount of tape is required to make the bearings fit snugly.

The tool assumes 1/2in from tool bottom to lathe center on a 8x16 lathe.

Order the Botmobile Kit from the MakerBot Store at store.makerbot.com/makerbot-botmobile.html and you'll have all the parts you need to get your printed Dune Buggy going in no time!

The wind in your hair... The sun on your face... The sand in your teeth... Everyone loves a day out cruising the dunes in their trusty Botmobile Dune Buggy!

The Botmobile Dune Buggy is an open source 3d printed remote control car that you can build at home. Using the Botmobile chassis the Dune Buggy was built from the ground up as a completely new type of remote control car

I think we can all agree, life would become much more interesting if I launched a turtle shell at you every once and a while.

But it’s no fun if I’m the only one with a shell to launch. Therefore…

Turtle Shells for Everybody!!!

All you have to do is print it out and assemble!

The Turtle Shell Racer is as fully 3d printable as I can make it using my Makerbot Cupcake CNC and its MK5 Extruder. The pdf file contains full assembly instructions and a parts list. This is a very ambitious project; expect to spend some time on it.

UPDATE Sept 26th

I have uploaded the modifications I made to the shells for the NYC Maker Faire.

Wheely Bar.stl - This replaces the rear axle brackets.stl with a wheely bar, which allows awesome wheelys!

New stearing Link.stl - This new link replaces the old steering linkage.stl. It is designed to capture one of the servo horns and allow a better connection between the servo and the steering.

Could not find a Deathstar on Thingiverse so I made one. This is in three parts. I made it so you could put a light inside. The light would shine through the small hole in the cannon dish. Feel free to make it better or with more detail. The picture does not do it justice.

Nope, not Dash Rendar, Ponda Baba, or even the young Lando Calrissian. It's your favorite smuggler Han Solo lovingly packed in carbonite for convenient shipping and storage. Enjoy Han Solo by yourself or with friends. Han makes a lovely conversation piece and will be certain to make you the center of every party.

I owe a special thank you to Sci-Fi 3d { scifi3d.com } and the awesome free STL editing package Netfabb { netfabb.com }

Inspired by the Z rod constraints on the Makergear Prusa.

You can print 2 or 4 of these and use them to eliminate all Z wobble on your Prusa.

I've included some before-and-after photos from cubes but the REAL visual proof will be when I reprint the OH shot glass.

SAME GCODE!

I made this in order to be able to orient my mechanical endstop vertically and thus gain a bit more space on my Prusa's x-axis.

I am using thingiverse.com/thing:10885 for my X-carriage and this lines up with the zip tie holes and secures neatly there. I have a makergear-style plastruder, not sure if this would fit with a different extruder or not.

This is a tool for bending lead of resistors and other components. Every line has a standard size, each slot is .05″ longer than the next and has radiused edges to make perfect bends without stressing the leads. It can be used to bend the leads of 1/2 watt resistors, 1/4 watt resistors, and diodes.
Esta pieza es una herramienta para doblar patillas de resistencias. Cada hueco es multiplo de 2,54mm (el espaciado estandard de componentes). Puede ser usado para doblar resistencias de 1/2w ,1/4w o diodos.

This device is a versatile dock for charging your iOS devices. iPads won't tip it over, and iPhones fit perfectly. Your 30-pin cable will be held in place by the channel in the bottom, an idea I brutally stole from Zaggo's iPhone dock. His thing is totally awesome, but it wouldn't fit my iPad as well, which is why I created this. The model was created in modo, and I've attached the original .lxo file.

Well, the obvious happened. I liked StefanHH's ball and socket (5578), but was astonished to see no actual helping hands design on thingiverse, (my apology if I somehow missed an existing design). So I decided to design one.

It is a puzzle. Impress your friends!
...
Well, impress the ones that don't know too much about 3d printing =)

I designed this tool to help me hob a toothed channel in a drive bolt for a wade's extruder. I've printed one, and used it successfully.

Ok, once you have an involute gear library AND a trapezoid thread library, you can easily make the simplest of worm drives, i.e. the non-throated kind.

Like all worm drives, the gear advances by one tooth for each revolution of the screw but with non-throated ones, there is only a single point of contact at any one time, and so torque and wear capabilities are limited.

UPDATE:
As I pointed out in the comments, AFAIK a trapezoidal profile for the worm screw is all you need to match the worm gear's involute.

To make them mesh, all I did was to make sure that:
1. the pitch is the same (distance from crest to crest),
2. the pressure angle of the gear is equal to the angle of the sides of the screw profile,
3. the distance between screw and gear is equal to the gear's radial pitch plus the screw's mid-profile radius, and
4. the twist on the gear is equal to the gear's pitch radius divided by the screw's mid profile radius, with a sign depending on the screw's handedness.

We have the pleasure to present (for the second time since Thingiverse is having some trouble lately) the ultimate rubber propelled X-Wing Car!

Scout is a printable tribot designed for teaching the Boy Scout robotics merit badge. scouting.org/scoutsource/BoyScouts/AdvancementandAwards/MeritBadges/mb-ROBO.aspx

I've marked this as a derivative of MiniSkyBot because I was inspired by it and because Scout still uses the wheels from that project.

The frame itself is a complete redesign with similar but different goals.

Goals:
Provide a kit that meets the merit badge requirements with parts totaling < $50 USD.

-Minimum printed parts
-Minimum vitamins
-Accommodate an arduino diecimila or nano.
-use a 9V battery.
-Flexible enough to allow boys to improve and extend the design.

The frame is a single printed piece. The tabs for holding the servo motors can be tapped with a 4mm tap to avoid the need for nuts.

The top holes can be tapped with a 3mm tap to screw on an arduino without nuts.

The bracket will hold a 9v battery with just friction. The rear battery bracket has a friction fit cup for a ball bearing caster.

Large holes in the bracket minimize the amount of plastic needed and allow wires to be routed up to the arduino.

Cost
Since affordability was a major consideration, here's a run down of the final project cost.

The plastic cost is just the cost of a roll divided by the number of kits we built. There was lots of plastic left over and the boys are using it to design improvements.

Frame & Wheels $7.86 (plastic from Makerbot)
Tires (2) $2.36 (Hardware store o-rings)
4mm bolts (4) $0.84
wheels screws (4) $0.96
Servos futaba (2) $8.38 (purchased new in bulk on ebay)
Arduino Nano $18.99 (purchased new on ebay)
Ultrasonic $3.90 (purchased new on ebay)
9v connector $0.81 (Radio Shack)
DC power plug $1.86 (Radio Shack)
9V battery $1.25
Total: $47.21

cleaned up the inside of the original object thingiverse.com/thing:609 using netfabb professional

A friend at our makerspace made a little engraver with some dvd burners, following this Instructable instructables.com/id/Pocket-laser-engraver/ (working surface : a bit more than a business card)

But I wanted to give it a nice structure (and maybe an enclosure later), this first version is even foldable :)

This OpenSCAD script provides modules for both Spur and Bevel Gears. It has some major enhancements over my original gear script thingiverse.com/thing:3534. It uses some of the spur gear nomenclature code from TheOtherRob github.com/TheOtherRob/MCAD with my own code for generating the involute teeth. The bevel gear is also my own work. Thanks also to elmom for some enhancements to my original gear script thingiverse.com/thing:3547.

Enhancements include the Bevel gear module, backlash settings, parameterised number of facets for the involute curve and whole of tooth generation to avoid some of the issues the original script had when mirroring a half tooth.

The STLs provided are not intended for direct use, but instead show examples of what can be done with the parametric script.

Parametric Involute Spur Gears take the following parameters:
number_of_teeth
circular_pitch or diametral_pitch: controls the size of the teeth (and hence the size of the gear).
pressure_angle: controls the shape of the teeth.
clearance: The gap between the root between teeth and the teeth point on a meshing gear.
gear_thickness: the thickness of the gear plate.
rim_thickness: the thickness of the gear at the rim (including the teeth).
rim_width: radial distance from the root of the teeth to the inside of the rim.
hub_thickness: the thickness of the section around the bore.
hub_diameter
bore_diameter: size of the hole in the middle
circles: the number of circular holes to cut in the gear plate.
backlash: the space between this the back of this gears teeth and the front of its meshing gear\'s teeth when the gear is correctly spaced from it.
twist: for making helical gears.
involute_facets: the number of facets in one side of the involute tooth shape. If this is omitted it will be 1/4 of $fn. If $fn is not set, it will be 5.

Parametric Involute Profile Bevel (Conical) Gears take the following parameters:
number_of_teeth
cone_distance: The distance from the pitch apex to the outside pitch diameter.
face_width: The length of the teeth.
outside_circular_pitch: The circular pitch at the outside pitch diameter.
pressure_angle: Defines the shape of the teeth.
clearance: Gap between the tip of the teeth on one gear and the root of the teeth on another meshing gear.
bore_diameter: The size of the hole in the middle.
gear_thickness: The thickness of the gear for bevel_gear_back_cone finish (see below).
backlash: Makes the tooth width smaller to make a gap between teeth of correctly spaced gears to allow for manufacturing tolerances.
involute_facets: As for spur gears.
finish: Specify either bevel_gear_flat(0) or bevel_gear_back_cone(1). If you don't specify this parameter you will get a flat gear for pitch angles less than 45 degrees and a back cone gear for pitch angles greater than 45 degrees. The example shows both with the small gear being the flat one.

Update: v5.0 Implements backlash for bevel gears (This was not working in v4.0).

This is an OpenScad script to generate modular and parametric racks, for a printable rack & pinion system for Reprap 3d printers, as a replacement for belts or threaded rods.
More info here : kaosat.net/?p=1670
Please note that this is an experimental , work in progress version

Edit 07/01/11:
-Added the herringbone version , in wich you can set the center angle (see schematic), that script can also generate the straight teeth with an angle of 0
-this version is cleaned up and optimized, and much faster to compile so please use this one preferably
-i haven't printed this one yet, and i am not 100% if all is ok

Edit 04/01/11:
-just a short video of a very very basic "platform" movement test : youtube.com/watch?v=8_KtJL7Gmto
-for testing simplicity, the motor is on top , but would ideally be underneath the platform
-i will try to have the herringbone version finished by next week

MUST resist the temptation to talk like Yoda.

He is about 1.5X bigger and less of the robe, more of the detailed face.

Turn your Dremel into a blower or vacuum. It works really well!

.75" ID output port, 2.15" inlet. Inlet bolt circle is 2.438" in diameter, and is for 6 4-40 bolts.

Printed on a Fablicator!

EDIT: The Impeller I believe is backwards. It still works very well, though. I'm going to re-print a mirrored version to see if it makes any difference.

EDIT2: The impeller works about the same despite being right or left handed. go figure.

My father was a carpenter. When I was little he made a whole bunch these intricate wooden Christmas tree ornaments that slitted together. So here is my MakerBot version of it.

Remixed with thingiverse.com/thing:10254 (spindle for Randyy's spool), and thingiverse.com/thing:11250 (one piece printable arms) to adapt it for the RepRap.

It's not very different from the original model, but I spend many hours in Sketchup tweaking it : correcting the scale in mm, getting rid of many mesh problems (face orientations and holes, especially in the hub), lower the height of the hub and the arms, join the arms in one piece like Fil did with the Randyy's ones, fuse the RotoScan's clip with the Tjhowse's spindle, organize the parts to be production friendly for a Mendel bed.
And finally present the whole in a "new thing" to make less works for the other who want to print that spool for their RepRap :)

For me it printed good, hub and spindle are maybe tight to clip at first but can spin freely after some movements, sometimes the dovetails can require a little sanding but its a really nice spool, thanks RotoScan !

Bebeme mucho is a combination of lips + lid [kissing + drinking]. It is the result of three programs: Trimensional [3d scanner for iPhone], Rhino [3d modeler], and MakerBot [3d printer]. The combination of these programs allows you to easily replicate and/or modify anything already existent in the world. Bebeme mucho is a playful example of contemporary making. Gift yourself.

This design was influenced by a thesis project by Gavin Johns:
