Print the mold and drill the holes. It should be 3mm diameter. get the holes close to the front. Be careful. Print the pattern upright as in the picture. use support when printing. Make a piece of thin sheet metal for bearing tops. Fasten with m2 screw. you can use it without any other modification on the old version. drill estimated holes for the engine. I added a screw motor housing. The last I added is the ABS model. Print this 2 symmetrically. Assemble with 2 metric screws. It will be more solid.
