Cap Mold Reservoir With Registration Marks

thingiverse

I designed this for use with making silicon molds with the intent to resin cast dice. To use, you would attach a die to this and put this in a tube (I'm going to use a few inches of 2" PVC pipe) sealed up with tape. After making the bottom half of the mold, you take it out of the tube, flip it and remove this piece, add mold release (or vaseline) and put it back in the tube to make the top half of the mold. I originally wanted to make these to fit into a 1.5" tube to save silicon, but it wasn't working size-wise. Even at this size, the d4 barely fit with the corner all the way into the triangular registration mark. If yours is any larger you may have to upscale one of them a bit.
