I made some kids toys, some RPG minis (also tried dice, but those didnʼt come out great), and some gadgets for my home like cable organizer's, towel hooks, a wall mount for a mirror, and the likes.

I know no way to recycle PLA (as in, you canʼt reliably make filament out of the cutoff and failed prints). Some say you can melt it and cast it using silicone moulds, but never tried it myself.
