Forma na včelí úly (alias vosí hnízda)

I recommend to print it from PLA (simpler) or ABS (used collar, 3DLAC for plate, closure box). 
Since there will be food contact, I used 5 layers. Resolution 0.2 mm.

It's a good idea to coat the inside of the mold with powdered sugar before use to keep the dough from stick. 

Then it goes by itself - see video.
