Good idea for old drill bits that have outlived their use. However…you can pick one up pretty cheap at Harbor Freight, so this is more of a project of love than anything else

I had one of these cars and they can take a beating, and for a small car, pretty roomy. So this is a nice build if you are young and need a cheap camper like car.

A D/C Motor that is. Interesting build especially for higher power DC motors.

Its fun to watch the video. Basically a light from the bottom lights up the parts for a camera to take a pic of and figure out what is what in shapes, then it picks them up and puts each type into different bins.
In this case its for the chinese Ender printer. But can apply to alot of other 3D Printers out there as well.

I got a kick out of this one. The one thing that worries me is the one end of the line for voltage is pretty much exposed and near the handle where your hand would go. And get zapped. Besides that, nice build
Nice and simple cart built for about $40 a cart. Me…I use IKEA like furniture to build carts myself, or stuff off the side of the road. Oh you could go even cheaper with standard plywood.

Nice idea, but…I don’t know if I would go as far as make my own spring, but just pull one out from the bin I have.
Nice build, author 3D prints the cast for making the mold, then prints out the rim to put into the case, and then adds in the rubber to bond with the wheel.
Basically re-uses the rollers from the printer to feed the paper across. Neat build.
