Turbines have awesome power in a small package. This one spins up to 60,000 rpm using the airflow of a standard vacuum cleaner, sounds like a 747 taking off, produces amazing power, and sucks up its own dust!

This is an opportunity for someone to make a successful product. I have no commercial interest, and would be delighted if anybody developed it further. A good start would be to source a batch of shafts and spacers for people to experiment with.

The spinning top is an simpler project, also there is a small hand-held turbine rotor just for fun.

A tilt-pan camera mount for use with FPV aircraft, robots etc. Its ultra small, ultra simple and ultra easy to build.

This optical endstop holder is used for a precise adjustment of the z-axis.

The basic idea of the endstop fixture is from Prusa's Mendel project (endstop-holder.scad).
github.com/prusajr/PrusaMendel

The basic idea of the vertical adjustment is similar to "Vertical Adjustable Opto Z Endstop Holder" from LittleDangerous

I've posted topics asking how to come up with the proper print temperature and read many posts as well. All that came back or what I read was "do it by trial and error", no one really gave any direction. The more I thought about it, the correct print temperature has to result in the highest bond strength.

So I developed this... The base is 25mm x 5mm, spindle is 10mm x 40mm.

Introducing the Baricuda Extruder for 3D Printing Sugar and Chocolate

Derived from the venerable MakerBot MK2 Frostruder, this air-pressure driven extruder ("baric") is a *U*niversal extruder because it adds a *D*egree *A*mplifier (yep... temperature) to let you extrude anything.

The Source Code and Files are Hosted on Github:
github.com/jmil/BariCUDA

We used this to precisely extruder sugar templates for engineering vascular tissues for regenerative medicine research. See the details here:
youtube.com/watch?v=9VHFlwJQIkE


You can use it for:
1) Molten Sugar Extrusion
2) Molten Chocolate Extrusion
3) Molten PLA and ABS and other experimental plastics Extrusion
3) Molten Extrusion -- This is a *U*niversal Extruder! Any thermoplastic material can be extruded.

You are only limited by your motherboard and the number of MOSFETs you have (for control of pneumatics just like the Frostruder).

Operation is IDENTICAL to the Frostruder, you just need to add a heating element and thermistor for temperature measurement.

DIWire is a 2D or 3D CNC wire bender that works like a 3D printer. Upload text commands or SVG files and it will print them out.

Spool holder for fillament spools. It uses 608 bearings(22mm) instead of the 625.

Here is "InMoov", the robot hand you can print and animate. You have a 3D printer, some building skills, This project is for you!!

This is a hand built for a job (still picture commercial), it was supposed to be mobile but not animated and mostly be able to take human hand positions. Cables or fishing rods might be added in order to control it, but it was not the purpose of this work at first. I am now working on another model(for the fun), trying to animate it, I really would like to do it with computer control but I have never worked in that field. Never used servo's before, so any help is welcomed.

A first movement video. I have to say that this video was not easy to do. I was holding the camera with one hand and trying to trigger the rods with the other.
I definitly need three hands!

I added code for mountings for a Parcan hot end with its peek block drilled with 30mm spaced M4 holes.
I have also added a parameter to add a filament guide which I know greg is not keen on adding to his design.

This thing provides the means to effectively manage cables on a stock Printerbot.

This is a redesigned prusa SAE x carriage, for the motor side. It was done in solidworks 2010, and is designed with printability as it's main goal. I had problems with overhangs, and thin parts breaking off, and this should solve those issues. Also, I hate gluing parts so I just added holes for bronze bushings in the support column. I'm getting ready to print this now, I'll try and post pictures when I'm done. Looking forward to comments!

Thi is a simple belt tensioner for Y axis. 3 in 1

1. Tensioner
2. Vibrations remover
3. Belt guide

This is a derivation of the "Enclosed Cable Carrier" by Landru

It is larger.

Hinge geometry changed for better movement, it takes more force to separate the links.

Completely redrawn (I've forgotten all that I changed).

Two styles of end pieces created.

Functional Pin Tumbler Padlock Model. User Print-To-3D: thingiverse.com/printto3d shared a very cool sectioned Paddle-Lock: js-kit.com/blob/sk9sIwQKzOFH1K4lciYmmQ.jpg that got me interested in making something that actually locks.

Again, all items are printable except for the springs which I removed from ball-point click pens (thankfully my wife is still putting up with disassembled pens around the house). This one is a little more complicated but it still works and makes a good desk oddity. If you were to glue the "Top", "Retainer", and "Lid" in place, the only way to get this lock open without the key would be to break it. But, what is the fun if you can't take it apart?

Note 1: I did do a bit of finish sanding on the components to make everything fit together and slide/twist well. I would suggest a "dry-fit" of the components with their mates before attempting assembly.
Note 2: The "Lock" component is a difficult print. I was able to get good results by adding two supporting features over the length and then carving/sanding it back to a circular form. If anyone has suggestions on how to print circular objects on their side, I'm all ears.

This is a Linear bearing LM8UU X carriage to allow quick change of Extruders and other tools on your 3D printer.
It has compatible bar spacing for Mendel, Prusa and MendelMax

*Update* 21st - March - Added Greg/Wade extruder adapter plate and all the Sketchup files so you can make whatever adapter plates etc. you may need.

*Added* 31st March - Belt clamp and Low profile catch together - as requested.

This is a DLP projector-based resin printer that can make very fine 3D prints in record time.

This is a work in progress. Today I plan to begin actual experiments with the resin.

I believe the basic design I am producing here is very suitable, however, the details of the design need changes in almost every part to be ideal. Most importantly, the vat should probably be much shorter, but the whole thing could be made significantly smaller.

I am currently using resin from
Bucktown Polymers:

bucktownpolymers.com/

(You might notice their price for resin is cheaper than some current PLA prices, by volume)

A2Sheds has provided a page with a few helpful resources, as well as the beginnings of his own DLP project:

code.google.com/p/lemoncurry/wiki/main

This is very much a work in progress. Expect more photos and videos to come.

Here's a link to my flickr site documenting this project:

flickr.com/photos/13723140@N04/sets/72157629564335469/

Next steps: Experiment with resin. Create working software stack.

Known Issues: Vat is too tall/big, glass may be too weak/thin. Vat probbaly needs a nonstick coating, like silicone or PTFE. Z Axis range is 5", vat is 5", so Z stage cannot quite clear the vat. A2Sheds recommends a heated vat to 50c so the resin flows better...

It is a proof of concept of a kind of printable spring. Initially I designed it for using in my Prusa Mendel, because the z axis springs were very difficult to find for me. Then I generalized the idea and parameterized the spring.

These springs conceptually consist of a strip of plastic that is bended. The outer cross section of the spring can be square, hexagonal or octogonal.

The spring parameters are:
* fid (fold inner diameter)
* folds: Number of folds
* th: strip thickness
* Drill: Drill diameter
* Diameter of the outer cross section

Here there is a video of the proof of concept:

Here are all the 3D printed parts for the RepRapPro Ltd version of Mendel. This is a three-head machine, so it will do colour and multi-material printing.

This is an adjustable wall mount for your monitor. It has a 100 x 100 and a 75 x 75 pattern to attach your standard mount. Simply print and connect with 8mm x 50mm socket head cap screws and a 8mm nut at each connection. You may need to file the connections to get them to fit into each other, I was trying to keep them tight to reduce drooping.

I do not know what type of capacity that it has. My monitor has not fallen off the wall yet. that is the only endorsement I can give. :)

Update 9/10/12
My monitor is still hanging on the wall without issue :)

Update: Corrected some dimensions in the SCAD

Inspired by the many attempts to create a spool holder.

The STL file contains a printable spool holder for the Cheap Chinese Spools coming from RepRaper.com.

The OpenSCAD file allows you to enter in just a few details about your particular spool, and hardware. After that you simply compile and print. These types of spool holders are great, but require care. If you let the filament get too loose, it will tangle. So be sure to keep tension on that filament!

Prepared STLs:
- PrintableSpoolHolder-MakerGear.STL
- PrintableSpoolHolder-RepRaper.STL

Noise & Vibration Dampeners for RepRap Prusa Mendel. Reduces noise, which is produced by the machine during printing, by more then 20dB.

The Bukobot Fly was originally made to test out some features of my Bukobot 3D printer prototype and experiment with thin layers. Then I got curious to see if I can actually make it fly..and I did!

First 3D printable hand glider?

Not sure if it's the first flying 3D printable mini airplane, but I couldn't find one anywhere that was small enough to fit on 8x8 platform and didn't require motors.

The Bukobot Fly has a 9" wingspan and 0.4mm thick wings.

VERY CHALLENGING PRINT!!!
This might be a tough print to do. It took me a few tries to get a decent first layer for the wings because the crappy PLA I had was very inconsistant in thickness... But if your platform is level and your material is good, it should work. Layer height should be set to about 0.1mm with a very flat platform and I recommend using PLA for the stiffness. Also, platform needs to be at least 7x7 inches to print at 100% size, not sure if it'll work any smaller, but should work bigger possibly.

UPDATE!!! I got video of it flying!!!

Attention: the distance between the smooth rod and the threaded rod is not the one of a standard lm8uu Prusa Mendel!

I don't have the equipment to do precision drilling for the lm8uu holders, and adding a belt tensioning system to the wooden carriage eats up Z printable space. So my solution is to design my own Y carriage with build in belt tensioning.
