Three-Part Mold Container
thingiverse
This is a simple container for holding parts for molding in silicone or other materials. Hold the two sides to the base with painters tape or the adhesive of your choice. The sides pull off after the mold has finished curing. I've printed these in PETG and ABS, and I imagine they would work fine in PLA as well. Hot glue seems to work well for holding parts to the base. Customize to the size you need. 4mm walls and a 0.4mm allowance seem to work well and probably don't need to change, but tweak as you see fit!
