The triforce from Nintendo's the Legend of Zelda

This is a project I am working on for my furniture design class. I am inspired in this case by Scandinavian design. The seat portion will be made of vacuum bagged maple ply wood and the legs will be made from walnut to contrast the colour of the maple. The padding is high density foam with a fabric upholstery. The head rest hangs with a weighted rod to counter balance the cushion and is secured through the chair via cut out.

Started out as an Aluminum Mendel and morphed into a bit of this and a bit of that. Mostly a learning exercise. An engineer printed the extruder for me in his commercial 3d printer. Made the Budaschnozzle with some modifications. I had a box of semi-circular half inch Thomson rod bearings given to me that necessitated using half inch rod. The bearings are very sensitive to clamping pressure and I would not use them again if I were starting anew. I used 80/20 stuff for most of the structure since I had a lot of scrap to choose from. No idea if any of this will work yet. I have Ramps 1.4 electronics to hook up to experiment with. That will be another learning exercise since this is my first build!

This is a device used for testing middle school students' structures. It is an improvement on putting a structure across two sawhorses and hanging weights from the structure!

I've used it for "Jinx Wood" bridge structures as well as sheet metal structures.

Check out my TeacherHann YouTube Channel - youtube.com/teacherhann - for videos of my students projects being tested to destruction!

Kudos to my colleague, fellow middle school Design and Technology teacher Gord McGill for allowing me to replicate his idea!

A member of msp3d.com wanted to model and print the replacement clip he needed for his door instead of buying one from Pella for $40. Done.

This is a fork
You can Eat with it
You can stab things with it
You can launch it with a device made to launch such objects


This thing has changed the world, can you?

This is a crude but working violin made in an 8-bit, pixelated style. Here's some videos of the thing in action: moonmilk.com/2011/04/17/8-bit-violin-played-by-real-fiddlers/

(It was on Make:Live on March 9th, 2011: makezine.com/live/)

It's laser-cut from 1/8" plywood (front and back faces), 3/16" plywood (bridge), and 1/4" solid wood (everything else). It's a messy design, and not fully refined, because I really didn't know what I was doing when I made it.

If you make any substantial changes or improvements to this design that result in a working instrument, please publish your version of the design to Thingiverse and tell me about it. And in general, if you make and/or perform with an instrument based on this design, I'd like to hear about it.

The document "8bit violin scratchpad" contains bitmap images I found on the net, and I don't claim any copyright on those.

This is a 3d Printable pig, with a large void inside for salt or pepper, and holes in the pigs nostrils to pour.

I designed it on a whim, when I was getting ready to get my MakerBot.

However, The part did make it into the NYTimes!!! nytimes.com/2011/03/05/nyregion/05about.html !!!!!!!

Thanks so much to the people who printed this before I ever had a chance to!!!

UPDATE!!!

There is now a V2 of the pig, all files have been updated! The tail of the pig is now the filling plug!
UPDATE 2!!!

There's now a V3 of the pig! no more toes lol, and the feet have holes in them so that you can push sugru in and it'll hold really well :-)

This little piggie's famous!

Here are plans for a simple caliper, handy to have around the shop for measuring thickness and diameters. Anytime I can build something that helps me build something else I am always pleased.

The plans should be as accurate as your cutter or printer is, I actually used this project as a collaboration for my laser.
