Useless box (dc motor gearbox version)
thingiverse
A sort of most useless machine (with a cheap dc motor and gearbox), that we use a lot in our workshops at the makerspace and during events to build with people for free :) Designed by http://www.thingiverse.com/Inouk and tweaked a little for lasercutting. Instructions use 363 x 173 mm of material (3mm thick) Full BOM here : http://wiki.nybi.cc/index.php/MostUselessMachine (costing roughly 56€ for 10 machines) The "doigt-v5" have a flag for cheap microswitch that don't have a metal lever, the version without flag is for more traditional microswitches.
