This is a pellet drum that uses the core of a Prusament roll as the body and a flange of the roll as a jig for making the drum.

It is rather loud so be wary :D

Print instructions

Files for printing on MK3S in PLA are included. The models are made to be printable easily even with 0.3 mm layer height. Tested printing with 0.3- and 0.15-mm layer height. Tolerances are looser with the lower layer height and tighter on the higher.

Difference from standard Prusa settings are 3 perimeters and the dangly bits need 100% infill to be heavier and a brim to stay on the bed. The drill jig can use supports, but you can get away by just cutting the droopy layers with a knife afterwards (if you forget to add the supports, like I did on the first run).

Face parts are probably best made with PLA for better sound, for other parts material choice does not matter that much.

While all parts can be printed in one plater, I would suggest to print the handle parts separately for nicer finish and a safer print.
