This is an awesome digger took a while to print but very nice. I used .2mm on my solidoodle 2 with not too many problems, does require a lot of support. Have the wheels printed but not on yet. I have included the zip but would like you to get the individual parts from the source he did a very awesome job on this, props.

These are Eagle v6.4.0 layout and pdf files for creating a PCB heatbed for the printrbot jr. The heatbed is mounted under a aluminum plate ([see here](http://www.thingiverse.com/thing:91504)) that acts as the printring platform.
In the PCB heatbed center is a little hole. Through this hole a thermistor is touching the aluminum plate's backside to measure the temperature at the plates center.
The PCB heatbed is cover with "plastik 70" spray for electrical insulation. (For PLA a heatbed temperature of max. 65°C is needed so the "plastik 70" should not decompose and should therefore be suitable in this application.)
The heatbed and sensor are directly driven by the stock printrbot jr. printrboard. Only a stronger power supply was needed (12V with at least 15A --> P >= 180W).
At the edge and top of the PCB heatbed a power LED with matching series resistor (both SMD) are soldered in place.


*) UPDATE #1: After one week of using the heatbed I can say that it works great. I did not flash the new temperature sensor's resistance values to the printrboard. It is close enough to the expected stock temperature sensor's range. If I set 47°C [117°F] in my pronterface interface I reproducibly get a surface temperature of 55°C [131°F] (measured with [this](http://www.conrad.de/ce/de/product/100980/) infrared thermometer).


*) UPDATE #2: Please remember to drill the holes in the PCB with a much bigger diameter as needed and use washers to compensate the bigger hole size. This is needed since the PCB and aluminum plate have different thermal expansion coefficient and if they were thightly fix to each other, without any play in the drill holes, the resulting stress could crack and/or destroy the whole setup.

Everyone has seen Raspberry Pi Computer, the credit card sized mini PC circuit board that cost only $35. Now there is a new Mobile Raspberry Pi called Pi-to-Go. Mini LCD, 10 hour battery, and 64GB SSD hard drive. You can 3D print your own case and build your own. Complete instruction on how to build this Pi-to-go computer can be found here: blog.parts-people.com/2012/12/20/mobile-raspberry-pi-computer-build-your-own-portable-rpi-to-go/

This is a knockoff design of the Aluminatus bed plate for self sourcers.

Includes 8 copies of the SIMO mount plate for 2060 extrusions and 2 groovemount plates, hidden in the large cutouts.

Also includes mounting holes for four bed corners (from the original Aluminatus) or two centered holes in the back (for Eugene_B's 3-point mounting system, linked in the Sources)

This is a printer frame based on the Air 2 by Mecano.

It can increase your print height by 60mm or 2.3 inches (depending on your hot end)

The printable height has been increased to 150mm (w/ Budaschnozzle) by extending the laser cut frame and flipping the z axis motors to the bottom of the printer. This printer can be assembled with the same smooth and threaded rods used for an Air 2 (The photos show a printer using 395mm smooth rods on all axis. The renders show the frame with the original Air 2 rod lengths)

This is a work in progress. Any and all suggestions for improvement are welcome.

**EDIT: Added low-poly versions of frame and motor brackets for faster slicing.**

Features:

* 190mm x 190mm x 150mm print area

* z motors flipped to bottom of printer

* printed braces for increased frame rigidity. (all braces moved to rear of frame for cleaner aesthetic.)

* the top acrylic brace has been extended to the back of the printer to ensure square and make room for printed braces.

* the crosspiece has been heightened / widened to increase strength and open up the build envelope

* cable / filament routing

* additional threaded brace / filament spool holder. (this is optional, but it seems to stiffen the frame. it is similar to Airwolf3d design but moved outside of 150mm printable area in z axis)

* all curves from RepRap Air 2 design removed in favor of chamfers

* unnecessary holes / slots removed.

* can use same "vitamins", smooth and threaded rods as or Air 2 (as shown smooth rods on z are cut to 395)

Design based largely on RepRap Air 2 by Mecano, ideas and parts from Lulzbot, Airwolf3d, and RepRapPro. thanks!

Heavy spools over time caused my spool holders to sag - so I remixed my remix with mikeq's spindle.

EDIT: You probably don't want to use this. It's too rigid. I'm currently using these: thingiverse.com/thing:22422 (I think mine's prettier but that doesn't count for much if the prints suck!)

If you need a rigid coupler these are great, but for most reprap applications (including the Printrbot Plus), give mine a miss. Sorry!

A simple coupler to mount M8 threaded rods to a NEMA 17 stepper. The up arrow points up!

I'm [no longer] using two of these on my Printrbot Plus and so far, [have changed my mind about them being] so good. (Don't overtighten!)

how to make a custom copper winding

This mount plate is designed for most commonly used 12mm diameter hot end groove mounts. It works with J-Heads, Makergear hot ends and other designs with the same mounting option.

It have been modified to raise 6mm up extruder, and allow a greg modified wade extruder reloaded to be mounted with big gear above belt clip.

It is machinable or prinable (ABS only!!!)

Derived from thingiverse.com/thing:55024, and redrawn with sketchup (sources provided).

As a guideline I had this very beautiful design of reprapdiscount:
thingiverse.com/thing:26093
But it was impossible for me to change it in a way to make it easily printable. So I decided to make my own version. But I wouldn’t do it without using the excellent professional made little elastic kill button.
While I created this case I had neither the LDC board nor the LCD. So “Hardwarekiller” send me, very exactly, all the needed measurements by email - and everything’s fits well.

2013 Southeast con robot. This robot will be full open source, but until Saturday morning 4/6/13 the files will not be open to public, ;)

So bad news, we lost. Yup, in the process of losing we developed a new term for amature mistakes. "Revpol" this is defined as apply voltage backwards, or reverse polarization.

Anyway, we will be uploading all source code soon along with a BOM. In the meantime until the team is ready to upload everything I will answer questions regarding the build in the comments as to get people going.

The 3D structured Ligfht Scanner is made of a Philips PicoPix 1430 Beamer and a Logitech Quickcam Pro 9000 for structured light scanning. The Couplings of the Mount are printed, the beams are Aluminium square pipe 20x20 mm

I made this for a friends telescope set-up to enable him to attach little mirrors and adjust their angle.

Could also be used to mount a variety of components, cameras, speakers, etc.

Edited to make the hole 7mm deep instead of 10, to make it work for deltapanel : thingiverse.com/thing:30330

This is based on the "Fully printable PCB vise", but I don't have glue with me, so I modded it with a dovetail joint, it might not be visually appealing, but it works!

A spiked wheel for 1:10 scale RC cars designed for winter bashing.

These have probably even more grip in the snow than normal tires in the summertime. Got to be careful not to turn at high speed as the truck wants to flip over due to good lateral grip. Had fun hill-climbing it on slopes I couldn't get up myself on foot :)

Designed for Turnigy 1:10 RC truck but the same attachment mechanism is used by other RC cars too.

Focus is a 3D printer that is designed to print using Selective Laser Sintering. Focus can also be adapted for FDM, 3DP and lasercutting/engraving.

I saw a few around and modeled one on richgain's version.
It's two parts, the duct and the bracket. You might need a different bracket as this one is made for a Greg's extruder. But if gives 16mm or so of adjustability in height for different hot ends.

NOTE: I have been told this will not work with Prusa V2, refer to the comments.

Inside I have ducted about 30% of the air to the side the fan is on and the other 70% around the revolve to blow from the other directions.

I based it on a 60mm fan because that's what I had on hand.

- Z axis concepts by **Quim Borras** and the spindle motor holder by **Misan** were really useful!! Also, **Diego Viejo**'s machine was of great inspiration for the Z axis (https://plus.google.com/u/0/photos/113930344830086538817/albums/5868944432651911713?authkey=CLDJgdehlN773gE) **Thank you all!!**
- This design woudn't have been possible without the encouragement of the **Panda CNC community** (https://plus.google.com/u/0/communities/102402711800402614517)
- Also, thanks to **Obijuan** (http://iearobotics.com) for naming the machine Cyclone :)

Steam engine cylinder, Double acting with D slide valve. This is just a teaser, more to come later.

Theses holders are designer to be fixed on the front theaded rod of Mendel Prusa, and allows fixing of a Deltapaner housing for reprapdiscount smart controller with LCD and knob. ( thingiverse.com/thing:30330 )

Initially, Deltapanel was designed to be fixed on the Tslot of a Reprap Pro.

With those holders, you can now fix it on a Prusa.

Sketchup files provided....

You can also have a look on knob for Deltapanel: thingiverse.com/thing:36690

This is a piece that must be put on a plastic cup cutted or you can made a similar cylinder that remplace the cup. It function is collect all the dust that is made when you drill a wall or roof.

With this system you can avoid waste the time cleaning all stained surfaces for the drill, because it will be trapped inside the "traps dust" and the plastic cup.

The height by the cup or the cylinder can be used to select the hole depth. It can prevent that the drill will be more deep than the wall anchor that you are going to put in.

To ensure that the "traps dust" stick to the wall, you must put around the drill, between the piece and the cup, a spring. The spring can be difficult to get it, for this, you can use the spring of a notebook.

Shower tray for 22mm bar

These are the parts that I used to make a 0.20mm nozzle for my Printrbot.

I put together a video of the process here:
