A filter box for an 80x25mm fan. The back end plate has a mount for a switch and a hole for mounting to a flexible light base.

This is the Snowman by ChristineBowyer except I added the following:
//this will flatten the object for dxf export
//comment out if you want 3D
projection(cut = false)

This allows you to export as a DXF file. If you want the version with thickness comment that line out.

This shield allows you to connect a HP C6602 inkjet cartridge to your Arduino turning it into a 96dpi print platform. It only uses 5 pins which can be jumper selected to avoid other shields. It is designed with a Arduino Mega footprint but fully supports both the Arduino and the Arduino Mega. It uses all through-hole components to make assembly easy even for beginners.

Features
Compatible with Arduino and Arduino Mega
Uses only 5 user selectable pins
Stackable (up to 11 Inkshields on Ardunio, 15 on Mega)
On-board 20V boost converter for inkjet head
Accepts 9-12V input via optional power connector or from the Arduino Vin
Auxiliary input header offers support for other microcontrollers
Auxiliary output header supports an extension cable to the inkjet head
Power and Pulse activity LEDs
ISCP header and Reset button
All through-hole components

A production run of this project was successfully funded via a Kickstarter here: kck.st/oAGeza

Description of files:
InkShieldLibrary.zip - Regular Arduino Libraries/Examples (You should download the *NEW* version)
InkShieldLibraryNEW.zip - Regular Arduino Libraries/Examples (updated version - found a few bugs when finishing the Mega version)
InkShieldMegaLibrary.zip - Arduino Mega Libraries/Examples
InkShieldLiteLibrary.zip - Minimal Arduino Libraries/Examples
InkShieldPCB.zip - Kicad Schematic and PCB Layout

This replaces the prior version. I added a version, "*_040pins", with larger pin holes to allow for larger non-stackable pins. The prior version works perfectly with female stackable header pins but not with many regular male pins.

These are modules for both EESchema and PCBNew in KiCad. They will allow you to make PCBs that have the appropriate header positions for a Arduino shield. I adapted files I found on the KiCad yahoo group (http://tech.groups.yahoo.com/group/kicad-users/files/Library/ArduinoShield.ZIP posted by axtz4) adding a version for the MEGA.

I have found many Eagle librarys but very few for KiCad, I hope this encourages others to use this great tool and share more KiCad files.

This is the handout and example files from a workshop I give at Metrix Create: Space. metrixcreatespace.com/

The goal of this project was to develop a low cost, open source inkjet printer utilizing standard inkjet technology, for personal use. This project was partly in response to the fact that there are no DIY inkjet kits available. There was a kit available from Parallax parallax.com/dl/docs/prod/robo/InkjetKitDocs-v1.0.pdf. This kit is no longer made and the book amazon.com/Inkjet-Applications-Matt-Gilliland/dp/0972015930 that was written to use that kit is now out of print.
The prototype design used a carriage assembly constructed from steel rods that were assembled using connectors that can be printed on an FDM machine. The entire carriage system is driven along the x-axis by a belt attached to a stepper motor. The print cartridge, taken from an HP point of sale printer, is driven along the y-axis by another stepper motor belt drive. The electronic controls use an Arduino Mega to run all of the printing systems.
The design resulted in a working prototype that fulfills all of the design constraints. The rod frame carriage design is lightweight, easy to assemble and easy to integrate with the other systems. The Arduino used in the electronics has a large library of resources available to perform things like LCD, SD card, and stepper control.
Areas where future work should be focused include making molds and casting printable parts to bring down the overall cost, developing host side software, and optimizing the speed.

An OpenSCAD file that can be used with other scripts to make teeth marks in your models.

This is my "Chick inspired by marshmallow candy" thingiverse.com/thing:7913 with bites removed using my "Parametric Teeth Marks" thingiverse.com/thing:7937

This is my "Chick inspired by marshmallow candy" thingiverse.com/thing:7913 inside the "Panoramic Egg (parametric too!)" by MakerBlock thingiverse.com/thing:7896

A chick inspired by the famous Easter marshmallow candy.

A simple parametric egg script. I have included a few sample eggs but the parameters allow for any size, "stretch", and angle. These parameters are clearly labeled at the top of the script.

A tray style case for a Freeduino (Arduino Clone) (http://www.nkcelectronics.com/freeduino-arduino-diecimila-compatible-board-complete-kit.html). It is designed to protect the lower portion of the board while still allowing access to the entire top.

There are variables in the OpenSCAD file that would allow you to adapt this to other round cornered PCBs.

This has been replaced by thingiverse.com/thing:9630. It has added versions, "*_040pins", with larger pin holes to allow for larger non-stackable pins. This version works perfectly with female stackable header pins but not with many regular male pins.

This replaces the prior version. Some of the pins on the Mega were incorrectly labeled. I also re-arranged some pins so that they made more sense.

This is a case design for Dangerous Prototypes' OpenBench Logic Sniffer. I added cut-outs for the various headers.

The holes were slightly off on the prior version of the file. I believe they are correct now.

This is a support to change the bed to a three point mount. It attaches to the 180 degree side of your froglet.

See my installation at: reprapbreeding.blogspot.com/2011/01/ceramic-tile-print-bed-part-2.html

I improved the overhangs (they are now 45°) and added mounting tabs.

I made this in OpenSCAD so that you can choose the level you want. I only tried through level 4 as it was taking a very long time to render at that point. The math should work for any level.

I had so much fun with the red and white candy cane on day 21 that I wanted to print the hat with two colors. I could not think of a good way to use the file as designed in two colors so I redesigned the hat to be a separate piece.

This is a modified version of the Day 21 part with a nicer, more realistic, candy cane.

This is just the x axis idler but with the number of faces reduced from 66160 to 7742. I was having trouble with RepSnapper crashing with the original.

This is a improved version of the coupling from thingiverse.com/thing:5002

I added some material to the top and flipped it over so that it can be printed without support. I also cut the knife edge off the lower tier.

These are all the gears needed for a Mendel with a Wade's Extruder. This was made using Rhino3D's contour function to slice the gears into 3mm slices.

Included are sliced versions of:
thingiverse.com/thing:4305 (Wade's Gears)
thingiverse.com/thing:2079 (Drive Pulleys)
Stock Z-axis pulleys

These cut out well and look dimensionally correct. I have not glued them together and tried them on a Mendel yet.

This is a second pre-release of the core files for the my development of an Integrated Parametric RepRap in OpenSCAD. These files contain the following:
IPR_DNA: All constants and calculations, the constants define all the possible things that make a specific robot unique. (ranging from desired build space to fastener and bearing sizes)
IPR_func: All "standard" modules, such as motor mounts, bearing mounts, hardware models, etc... currently this file "builds" the main frame out of the hardware specified in the IPR_DNA file (as seen in the attached pictures).
IPR_parts: All the actual parts you would print.

Currently there are some printable parts (although still untested):
z-axis bases
guide rod clamps (based on thing:3437)
z-axis lifters (inspired by thing:4428)

And some unprintable:
Vertexes (with no holes)

A basic man made as a test using MakeHuman. makehuman.org/

I made this in an effort to explore printing the human form on my printer and to learn how to use MakeHuman.

The .obj file has the whole body while the .stl files are just torsos.

If you look at the .obj file it has jaw bones, teeth, eyes, and extra "joints" (little closed polyhedrons floating inside). I believe I removed all of those extra bits in the "***test2.stl" although they did not cause me problems when printing the "***test1.stl"

These are experimental simplified versions of the guide bearings for all three axis on a Mendel type printer. They are NOT direct replacements and will require other modifications to work.

These are a part of my Mendel/Huxley "remix" currently code named "Mindel" (for MINimal MenDEL) (UPDATE 11/26/10 - project renamed "Integrated Parametric RepRap"). These are not ready for prime time but I am releasing them now in the spirit of "release early, release often."

Follow the progress at reprap.org/wiki/Integrated_Parametric_RepRap

A version that prints even better. It still has options for necklace or key-chain holes.

The "Smooth" versions have had a trip through MeshLab for some smoothing and face reduction.

A version that scales down better. It also now has options for necklace or key-chain holes.
