This is the real deal, no derivatives here. These are the real Printrbot in it's current version. I have a bunch of these printing all day, every day.... it works. It is expandable to larger widths and heights easier than any other reprap out there. Period. Its the most inexpensive bot out there being mass produced. And, its now yours to print, build, improve, change.... whatever you like. I can't wait to see what you do with it. I will post pics of all the various forms it takes, news, etc at printrbot.com

UPDATE: I made a new version of the Cookie-Cutter-Editor
local-guru.net/blog/pages/cookiecutter-editor


Recently some very awsome cookiecutter-designs started to show up on thingiverse (like the escher cookie cutter ( thingiverse.com/thing:3207 ) or the jigsaw cookie cutter ( thingiverse.com/thing:3267 ), and many more) (and one of the local radiostations has played "last cristmas", because it's only 6 months till x-mas O_o )

So i thought about how the generation of such custom cookie cutters could be simplified and i developed a custom cookie cutter generator in processing.

read more about the project at my blog post
local-guru.net/blog/2010/06/27/custom-cookie-cutters-for-the-makerbot

Build plates for the full sized turret chess set suitable for printing the whole set, with both colors, all at once with a MakerBot Replicator with dualstrusion. If you're feeling extra ambitious, I've also included a version with the entire chess board (split in half) as well as all the pieces!

This hasn't been tested yet...

This has been the ultimate project for me, and is now finally functional after 8 months of blood, sweat and ABS.
It is also made on my 3d printed makerbot ( thingiverse.com/thing:3285 )

The printer can easily get taller by adding more z-elements and replacing z lead-screws and wobble arrester bars. I would then end up with almost 800mm build hight.

It wouldn't surprise me if this is the largest printed multi-piece object, as it is built from 15+ lbs of ABS plastic.

The Klein Bottle is a bit like a mobius strip but without the edge. There are many flavors that a bottle can take so this model is only one of many representations that can be imagined.
A really fun feature about this shape is that you can fill it with liquid on the same face that the model can then rest on.

This is a Klein Bottle.

We were asked to make a good ol' American made B-17 Flying Fortress. So, here it is.

Idea submitted by Matt Goldeck to the GE Air Show at Facebook.com/GE

The model was created in Autodesk Inventor 2011, using only 90 degree angles to maintain its rigid appearance. It was designed to stand up on a desk or computer, and was inspired by the increasing popular game called Minecraft. Additionally, the design was meant to test the makerbot. The Creeper is a close to exact scale model of the one in the game. It was supposed to have 4 legs instead of 2 but I decided to have 2 because it would be more structurally strong.

Due to the laws of physics, the original print didn't turn out exactly as i wanted it to. As you can see by the attached images, the mouth sagged a bit because the Makerbot was forced to extrude the plastic in mid air (as it prints layer by layer). I then refined the original design to prevent this from happening by increasing the width of the bottom of the mouth.

A 2D multi-tool design that is meant to work on 1/2", 7/16", 3/8", 5/16", 1/4", and #10 hex bolts as well as hex screw bits, and it has a bottle opener. I gave it away as the "Claire's choice award" at the Atlanta mini-maker fair at Georgia Tech (our mascot is a yellow jacket, which is why it looks a like a honeycomb). I hope to improve the bottle opener design soon.

This is a Collaboration between MakerBlock and I for the MakerBot United Competition. And we now have a new collaborator syvwlch! If you like it, please click the 'like' button!

These are a set of Windup ChatterBox Teeth, like the kind you get in gag stores or the kind "The Joker" always seems to have in "Batman". The two toned teeth are of course achieved by changing the filament at the proper time during the print. The wind-up portion is driven by a clock spring, which you can get from any old wind-up toy (or a wind-up clock, but why would you want to destroy a clock?). I got this particular clock spring from a Dollar Store Easter Toy, you can see the pictures of the Harley Riding Easter Bunny I sacrificed in the instructions.

The Drive Mechanism is a Geneva Drive, which is pretty common for a wind-up toy. You wind up the spring and it rotates a cam shaft, opening and closing the teeth. Unfortunately, we could never get the mechanism to work properly. The teeth chatter of course, but the problem here is they chatter too fast and the clock spring expends its energy WAY too fast. We still have a few days left in the competition, so if anyone thinks they have a solution for this and would like to collaborate, speak up now!

We have tried every thing we can think of and are at our wits end. We thought gears would produce enough friction to slow the clock spring down, but they don't!

This is a derivative of thingiverse.com/thing:4458. When I built the shorty version I had trouble getting the parts to print correctly and I wanted the ring to turn further to fully open the box.

When I designed this iris box I started from scratch and used a different mechanism to open the box.

I have also uploaded the NX6 .prt files for anybody who wishes to use them.

In the tradition of barrel of monkey's these guys are meant to link together en masse. They can form chains or even checkered sheets by connecting on all four corners.

This thing was originally conceived and designed by MakerBot's own Matthew Griffin (http://thingiverse.com/mifga). Enjoy and please send comments, we're still working on it!

Check out v16 for our latest and greatest version! the sc55 version is the version that they are printing at MakerBot lately....

This caterpillar track is the first step towards designing and building a printable mobile robot. My finished robot will have four of these modules, but many other designs are possible. A single caterpillar can function on its own as a simple robot that can move forwards and backwards; two modules can be joined together to form a tank-like machine, etc.

This thing is designed to work with a Futaba 3003 servo (modified for continuous rotation) and uses O-rings to make up the transmission and the caterpillar itself.

Transmission O-ring: 3mm thickness, 60mm diameter
Caterpillar O-rings: 3mm thickness, 124mm diameter

This O-ring system was chosen because it was easier to prototype, but it has evident drawbacks. In future revisions I will change it to a "solid" rubber track.

Note that the pictures of the printed robot at the bottom of the page are missing the reinforcement parts. I will upload new pictures as soon as I modify it!

I've taken all the calibration prints out there and condensed them into one place. I have here:

.5mm thin wall
20mm box
20mm hollow box
50mm tower
perimeter width/t tester
precision block
overhang test
oozebane test
bridge test

and more to come.

All designs are my original work and not taken from other users. But they are inspired by other users.

The 20mm box, thin wall, and 50mm tower are ideas from Spacexula's great calibration set thingiverse.com/thing:2064, and the other ones are my ideas and not influenced by others. After Spacexula's calibration set, there is quite a derivative tree.

Here are some combos I have found with my MK5 extruder:
(In order of: Layer Height, Width/Thickness, Feedrate, Flowrate PWM)
.36, 1.528, 34.1, 255
.3, 1.789, 42, 255
.2, 2.521, 35, 197 *This is still experimental, most prints I try with it fail :(

A nearly full size (for the toy) monkey to replace missing ones from your container full of primates (name changed to protect me from the copyright beasts). The texture is a little rough (fur details are still in their infancy in Makerbot printing) so you might smooth it out by immersion in acetone for 20 minutes or so. Try printing them in the appropriate ABS colors.

These bots were designed to be able to interlock and stack together.
I've included a boxy version and a smoothed out version. As well as a small size and a large size.

An adjustable solution for the business card displayer that will fit onto the Makerbot build platform. Could be used to prop up things of many shapes and sizes.

A printable harness to prevent your cables from falling into the abyss when they are not in use. Keep yourself organized and save the frustration.

The STL is optimized for USB peripherals the same size as the one that comes with a Makerbot. If you want to fit a different sized cable, scale accordingly.

This is a new and improved heated build platform. It is lightweight, compact, lower cost, and sexier than the old heated platform. It is also easier to put together and simpler in construction.

The major breakthrough on this board is twofold:

1. We use a PCB for both the heater element and the support circuitry.
2. We use a lasercut aluminum heat spreader for uniform temperature.

After a bit of trial and error, we came up with an optimum trace resistance of about 4.5 ohms which gives us a 30 watt heater at 12v. This allows us to get up to 100C pretty easily (under 10 minutes).

These are the printable parts for a filament spindle box.

The housing is build from wooden parts without need for a laser cutter (only rectangular parts, easily available in most hardware stores/home improvement stores).

I wrote down the whole project in detail in my blog post at
pleasantsoftware.com/developer/3d/2010/07/29/chipboard-screws-are-the-new-nuts-and-bolts/

[UPDATE] I slightly changed the design to have a window in the front. I also added detailed drawings for the box itself to this thing (see below).

Here is a squeeze buckle like you normally have on a backpack or hiking gear. I removed all of the supports for a strap on the fork part, since it just wasn't printing properly.

Also the fork fits into the sleeve in only one direction, due to the edits I had to make to make it printable.

Enjoy!

Here are some miscellaneous toolholders that can be scaled to fit practically any tool.

I was in the market for something like this myself, and was looking around searching for toolholders. The problem however is that there ar alot more different sized tools than there are toolholders that match, so then you end up with something that just looks awful and doesnt fit 100% to anything.

So regarding this project the goal was to make many different shaped toolholders that could easily be customized to fit any tool.

And again a big thanks to the makerbot crew for the plastic that made this:)


(Just an FYI - Everyone of my toolholders are printed on my full size makerbottable makerbot thingiverse.com/thing:3285)

A simple conveyor belt build platform for the MakerBot. It enables the MakerBot to do multiple prints without user intervention.

This is an initial prototype that does not support a heated build platform. I intend to add HBP support at a later time. I'm also still playing with conveyor belt materials. I've started with some Duralar I picked up for an art supply store. It has held up ok so far but more experimentation is required.

The intent here is to get the design out so people can play with it.

There are some tools that are nice to have close to you when you're a MakerBot operator. I made this little tool rack that is easily mounted on the side of the MakerBot. It holds three sizes of allen keys; One for the M3, the M5 and the M8 bolts. It also has room for a little adjustable wrench and a standard flathead screwdriver for loosening or tightening the wires on your extruder board. It also has a hook that I use to hold the hot pad for handling my Heated Build Platform

I've also provided the SketchUp source files, so feel free to modify and improve it!

NOTE: there are two versions. One just have normal holes and hexagonal holes for the allen keys, while the other has drop-shaped holes to obey the 45-degree rule. I've actually found that with the right settings I was able to print the non-dropshaped fairly well, so that's the one I used.

What's cooler than transformers? A Cupcake CNC transformer with a Bre head? This is a fully articulated assembly that transforms from a Cupcake CNC to a Bre-bot.
I started with a snap-together design (see the attached concept sketches) but migrated to a bolt-together kit for various reasons. The final design allows for fine adjustment of the joint tension so the transformer can stand in any position but still be movable, positionable, transformable!

See the animated transformation here: jmillerid.com/wordpress/2010/05/cupcake-cnc-transformer/

Modeled in NX6, rendered and animated in Modo, .stl files cleaned up in Blender, exploded view created with Rhino and Illustrator, sketches with Sharpie.

I 3d-ified the design by stickoutrock and made it so the crosslinks snap into place.

Step one: Print one of each, but you will need two caps.

Step two: Assemble wheel onto base then cog wheel.

Step three: Press or glue pins on axles.

Step four: Spin wheel in amazement!

Beco Blocks are 3d printable, snap together, ball and socket based building blocks.

Initially created as a prototype for another ball and socket based project, these blocks functioned so well I decided to make a number of variations to allow the creation of more complex objects.
