I tinker with electronics, which means that I have a whole lot of little wires called jumpers. Keeping jumpers in little storage drawers is not a very good solution to the storage problem. So I took my design for the pegboard canning jar lid (http://www.thingiverse.com/thing:567374), poked some holes in the top to create a jumper storage jar / dispenser.

Print the pegboard friction slider with supports. Do not use supports when printing the canning jar lid.
