Petri dish rack for 100 mm plates

I designed this one myself, since the other designs were all very massive and solid, which cost me too much material.

It is for big petri dishes and can hold up to 5 pcs with 100x21 mm size.

This one uses a hexagonal lattice design, which when printed out, weights only 30-50 grams, instead of 200. Also, the print time should be a bit faster.

I printed it with PLA, but I recommend PETG or something more stable, since it deforms very fast when the dishes come out of the autoclave. But PLA still works great!

Edit: I also added a reinforced model. The strands on this v2-model are now 2 instead of 1 mm thick, which should add some robustness.
