Painter's pyramid kèm holder

To make painting of parts easier I made some painter's pyramids to elevate the workpiece (thought there must be a better way than putting nails in strips of wood every time.)
There are already a lot of designs out there, but I wanted to roll my own, of course 😁.

I didn't want a bunch of pesky pointy pyramids kicking around in my tool storage, so there is a holder to keep 12 tetrahedra together: just push them in from the bottom and pull out at the top of the holder.

Printing:
I printed in PETG, nozzle 0.6mm, layer 0,25mm
