My thing has no expecific function, it´s just a composition of two objects that interect with each other.

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results soon.

This thing is small! You can make this using a few laser cut parts and your MK4 extruder hardware. There are a few tweaks I need to make, but it's closer to the final design. For more information see my blog post charlespax.wordpress.com/2009/10/30/paxtruder-0-2 .

The simple object to test the maximum overhang 3D printer can deal with. The angles are, top to bottom:


90°
80°
90°
70°
90°
60°
90°

180°

90°
55°
90°
50°
90°
45°
90°
40°
90°
35°
90°
30°
90°

In short, the bottom part is 80,70,60 that should work on every machine and the top part is 55-30 in 5° steps so you can then find what overhead angles you can "live with", what the "good" ones are and what angles are unprintable.

EDIT:
I have now added also a test_overhang_flat.stl after imho valid comment that overhang on the round and flat surface is not same, so here's the one to test the flat overhang.

One side (right) is 60, 55, 50, 45° (with 90° in between) and other side (left) is 40,35,30,25,20° (with 90° in between).

INTRO
It seems to be the month of construction sets on Thingiverse, so here is another entry in the category.

Contraptor is a DIY open source construction set for building Cartesian robots. It is basically 1" aluminum Erector set with linear motion extensions. While it's in development and sometimes things don't work as they should, functional robots have been assembled from it: contraptor.org/contraptions

The set is designed to be made with the simple tools of a basic workshop. A lot of materials for Contraptor like aluminum angle, threaded rods and fasteners can be found in a hardware store. In the spirit of modularity, it uses Makerbot/Reprap electronics and Arduino/Sanguino controller.

In addition to DIY plans, we're working on Shopbot-able kits that can be manufactured in small quantities by anyone willing, from open source drawings.

Contraptor components and assemblies are modeled in Sketchup and are hosted on Google 3D Warehouse, mostly for ease of accessing from within Sketchup. Thingiverse is the best place to host DXF/SVG sources and part lists for components, so there will be more Contraptor things coming (hopefully including printed ones from the community :).

Apologies for the long read, on to the thing:
/INTRO

Perforated angle comes in lengths from 1" to 24" and can be used as a structural component, as well as a linear motion rail for sliding elements. Attached DXF file and part list are for 1-ft long perforated angle.

The breaker is a small intelligent guy. He supports himself with arms
and legs inside a plastic globe. Because of the ball, he can do a lot
of different moves. Underneath his cap he has a lot of weight to keep
him balanced all the time. In addition, without the globe he performs
well on his arms and legs.

I made some metabrick at the Providence Fab Lab. I scaled it for 1.6inch Delrin, so it didn't come out correctly, but it still snaps together.

Ornamental cloud, can be used for example as as a brooch.

A simple printable tool for getting the most out of your tubes of toothpaste, lotion, etc.

At a recent trade show, I noticed an astonishing amount of beauty and cosmetic products using the same toothpaste tube-like storing containers. By the end of it, the representatives were struggling to give out samples while the tubes were taking on that all-too-familiar form. ( re-nest.com/uimages/re-nest/toothpaste.jpg )

I couldn't help but think about how I would solve this problem with a (hypothetical) makerbot.

The slot width is made to fit the largest of flattened toothpaste tubes found amongst my friends.

The front slot is drafted just a touch to ease the initial insertion of the tube, and the large circular surface is intended to get that last extra bit once the squeezer reaches the back of the nozzle.

This design uses a total of 2.7 cubic inches of material.

Back in July Switched.com challenged us to design and make a set of salt and pepper shakers, all in one day! We took care of the design end, and the shakers were made by awesome 3-D printing technology from MakerBot.

We've always wanted to design a set of salt and pepper shakers to match Egg Pants, one of our most successful products. This finally gave us the chance to do it. We bring you Salt and Pepper Hats! We're so happy with how they turned out that we will be taking them one step further and turning them into a product for our line, which should be available by winter 2009.

In the meantime, we're offering up the files for our prototypes - download away and make your very own! Want Egg Pants to go with them? Get a pair here: designglut.bigcartel.com/product/egg-pants

This is a drag chain for the MakerBot extruder cable (or any other cable/wires).

It keeps your extruder cable out of the Z-stage belt and let your MakerBot look professional (kind of...)

The objects need very detailed printing in order to work. You definitely want a good tuned MakerBot and Skeinforge settings to print this (don't say I didn't warn you!).

The ZIP file contains GCode files for all objects, including 6 or 8 chain links on one raft. It might be the best to skeinforge the gcode with your own, tuned settings. The included GCode files worked for me (resp. my MakerBot), but (again): these are some really hairy objects to print.
