Useless Machine Arm
thingiverse
This is a design for an arm for a Useless Machine. I was building one for my Dad for Christmas, and rather then cut out the arm in wood, I designed this to be printed on my new 3D printer. Instructions Build a useless machine as described at http://makeprojects.com/Project/The+Most+Useless+Machine/91/1#.UNJnFOAZ-lg Instead of cutting an arm out of wood, print this design. You may have to tweak it based on your other design choices. I have included my OpenSCAD source file if you need to make changes.
With this file you will be able to print Useless Machine Arm with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Useless Machine Arm.
