I wanted to display a "ShutUp&Hack" as during the UnlimitedDesignContest ( flic.kr/s/aHsjvcr15A ), didn't had the file and can't find something like that on thingiverse or the web...

So I remade it quickly :)

(the "-120" are a little more packed to be stronger)

Based on Jetty's buzzer Support (http://www.thingiverse.com/thing:16170), this hack uses a common household wireless doorbell system (instead of a piezo buzzer) so when your bot is done printing it triggers the receivers to chime throughout the house. I have two wireless receivers in different locations in the house linked to the makerbot. A different sound is triggered by the bot than by the actual doorbell (could be confusing otherwise!)

It's handy to have a small rack to hold PCB's while you're building them. This little rack is printable in sections of 4. The racks snap together with dovetails, and have screw holes for mounting to a large board.

This speaker is a quick mod of thingiverse.com/variador 's tripod mount. It had such an amazing pressfit I thought it would be cool to see if I could make it into a speaker. Print it out plug your phone in and listen to your beats out loud!

For a video demo check this out:

This requires the makerbot 3d scanner "cyclops" kit. It does not allow derivatives but it is located here... thingiverse.com/thing:4271

Sorry for poor documentation but the text and photos should be sufficient for those who are interested.

These printed parts are used to help the Optoma PK201 Pico Projector fit into the laser cut plywood housing of the Makerbot Cyclops 2.0 3D Scanner.

The wheel part allows you to adjust the focus of the projector whil it is in it's housing. It needs to have a rubber band or o-ring placed around it to give it sufficient grip though.

The cube part is placed against the bottom right rear corner of the scanner as you look into the lens, and acts to keep the rear of the projector in the correct location.

Some modifications are needed to the laser cut plywood parts too to accommodate the non-standard projector and these additional pieces. The hole on the rear panel needs to be enlarged, a hole for a bolt to hold the 3D printed focus wheel needs to be made in the bottom panel, a wide slot on the right panel needs to be made for the edge of the focus wheel.


The bolt hole for the focus wheel is 3mm in diameter with its centre 26mm from the front edge and 10mm from the left edge of the bottom panel
The slot on the left panel is 8*30mm with its bottom left corner located 20mm above the bottom edge and 13mm from the left edge.

The enlarged slot on the rear panel is 20*62mm with it's bottom left corner located 13mm above the bottom edge and 32mm from the left edge.

You will also need to enlarge the hole in the front of the device to allow the lens from the pico projector to project properly. The hole should be rectangular about 20*15mm starting 18mm from the bottom edge and 45mm from the left edge of the front panel.

Method for constructing a Negative-Pressure Activated-Carbon Fume Chamber.

Eliminate ABS fumes/smell when ventilation to the outside is not an option.

Compatible with HBP and APB.
Costs about $35 and runs at about 4 Watts.

I've been creating a sculpture, the Anywhere Organ anywhereorgan.tumblr.com , for the past year or so. It's gone through many iterations, modifications, revisions, and changes over time but is finally coming together into a predictable, robust sculpture.

I designed these parts as a system to take salvaged organ pipes and create them into a huge extended instrument, networked together and controlled by MIDI. Organ enthusiasts have been saving dismantled pipe organs from the dumpster for years, but many don't have the time or resources to use all the parts they acquire. I've found they've been very eager to have me take random or incomplete sets off their hands. As my own collection grows I'm hoping to add to the Anywhere Organ, eventually having the mobile equivalent of a cathedral organ I can take anywhere from an underground cave, to an abandoned theater, to a fire escape and play.

I've been doing a Kickstarter trying to raise funds for the next bigger, better version. Please give it a look, tell your friends, and donate. kck.st/anywhereorgan

All of the DXF's are designed to be cut centerline on an industrial laser out of 3/4" nom. (.719") indoor plywood.

This document was created as a way to release what I've learned and built through designing the Anywhere Organ. It is not intended to be a tutorial. It is intended to help folks get on their way to building their own organs, laser cut instruments, and huge awesome things. At some point I may tutorialize, but the path to the design I now have has been so long and winding it is difficult to put down concisely into a Thing.

A screw came loose on the metal baseplate of our dishwasher and I couldn't manage to get the screw to line up with where it seemed like it went. So, I whipped up this little doohickey to hold the baseplate in place.

It's a quick OpenSCAD hack. Not sexy, but it works.

From the time I fired up OpenSCAD to printing was probably about 10 minutes total. I printed slow and steady. OpenSCAD firing up to fix was about 30 minutes total.

The MK7 is great. But one thing never made it into the design spec: the ability to switch filaments mid-print.

Switching filaments enables multi-colored prints without fusing filament first. It also ensures that if you run out of a given filament, you can load new stock mid-print. This is very helpful for long prints.

The MK7's Stainless Steel Thermal Barrier Tube is not seated close enough to the Knurled Pulley, which makes it nearly impossible for a new filament to chase another into the Tube. However, raising the Tube ~3.5mm brings it close enough so that the new filament will not bend or slip off the old filament as it enters the Tube.

Another benefit is that you gain an additional ~3.5mm in Z-height!

Here's some video of the results youtube.com/watch?v=I25pOHE91xY

UPDATE: Zach posted a solid filament block for the MK7, so you should print this out and modify that instead of your purchased one. thingiverse.com/thing:12147

This is sort of a derivative work of ToM Extruder Relay Fix by M_G thingiverse.com/thing:9130
Which is itself a derivative of ToM Extruder Relay Fix thingiverse.com/thing:5569 by MakeALot thingiverse.com/MakeALot

This uses transistors instead of Relays. Perhaps some will find this useful if they don’t have access to relays. A variant of the ToM Extruder Relay Fix for dying extruder motors that operates in the forward and reverse directions. This thing uses 4x NPN Transistors, 2x resistors and 4x 1N400X series diodes.

I have not yet built this myself though!

Perhaps some will find this useful if they dont have acces to "Double Throw" relays. A variant of the ToM Extruder Relay Fix for dying extruder motors that only operates in the forward direction. Uses 2x 12volt single throw relays, 2x electrolytic capacitors and 3x 1N400X series diodes.

This is a (untested) replacement hull for
TI-30X, TI-30Xa, TI-30Xa SOLAR, .. ?

I'am sure I'am not the only one who has a broken one -_- .

Hopefully you can just use the *.stl file.
The *.scad code is an ugly hack I stitched together somewhen in 2010.

It has an optional endorsements on it.
Beware rendering with endordsements takes a hell of a lot time.
With a bit more hacking you can choose from some planegroups.

I wanted a proper board to mount the MAX6675 sensor discussed here: reprap.org/wiki/Hacks_to_the_RepRap_Extruder_Controller_v2.2

Datasheet is here: datasheets.maxim-ic.com/en/ds/MAX6675.pdf

I haven't attempted to use it yet, but it etched cleanly and I had no trouble getting the chip to seat on the pads. There are pads to mount a .1uF capacitor as well, but damn those things are tiny and exactly the same dingy-beige as my carpet.

I'm better with CAD than I am with Eagle, so I welcome a proper Eagle version if anyone wants to put in the time.

Meanwhile, I'll be under my desk with a flashlight and a magnet hunting for capacitors.
Damnitallsomuch.

This is a very minor hack to Schmarty's excellent Unicorn G-Code Extension for Inkscape. Now when you create some GCode with Inkscape, it can autohome the XY platform before registering and printing. It incorporates the "start.txt" and "end.txt" from my autohoming code. thingiverse.com/thing:6741

The inside handle on my front door broke off. I could use my finger to open it but I wanted a way of forcing it to stay open.

My first attempt was a 16mm x 70mm tube (inside diameter 10mm). Unfortunately it wasn't quite wide enough to hold the catch open fully so instead I printed this little two-tone cone to jam into the catch.

It fit perfectly and did the trick!

This is my first ever 3D design and also my first time using OpenSCAD. I'm mainly documenting this on Thingiverse for my own record but I'm releasing the files into the public domain so anyone is free to do what they like with them.

I've also uploaded a version 2 of the cone. I wanted to keep the cone manifold while ensuring the wall thickness stays at a constant 3mm. The first version was manifold by having the inner cone longer than the outer cone but the downside of that is the inner and outer walls aren't totally parallel so the wall thickness won't be constant.

Comments appreciated I'm still getting to grips with OpenSCAD.

Allows for the laser etcher to be used with the cover open by placing 2 magnets at the cover open detector. After you cut the piece and fit two 1/4" dia Neodymium magnets in the holes (polarity does not seem to matter). Place this the in the lower right hand corner of the cover rest that's it!

Today was Fashion Hacking day with Diana Eng at NYC Resistor and I've wanted to make these keyboard pants for a long time. The basic idea was to take a flexible silicone keyboard and somehow integrate it with some pants (or shorts). I had they keyboards laying around for a while and I ran down to the Conways to get some jeans for about $8 (Yay fulton mall!)

This was inspired by a cool project I saw a long time ago on the hypernets: engadget.com/2008/04/23/keyboard-infused-pants-make-it-okay-to-grab-your-crotch/
