>>5316105Yeah, just buying a benchtop injection mold is about 4k, then you've got to make resin or aluminum molds on top of that. The Gingery home-made injection mold starts by assuming you've got a bench-press handy, so that's right out...
>>5315113I'm pretty sure the round burr bit I use is the Dremel 191 (B0006N72XE). You can also find grinding burr bits (they'll usually specify "diamond") but I prefer a cutting bit because it's faster.
A pin vise is a handheld shaft taht you turn instead of a motor. You fit a bit into a collet, then hand turn it. They're common among modellers because a motor tool will burn through thin polystyrene sheets in nothing flat.
If you're not using polystyrene sheets or delicate work, I'd just as soon recommend getting a cheap Dremel knockoff and save some carpel-tunnel.
