Subaru Justy EF12 Eric style working engine model

So here is WIP version of my EF12 working 1/3 scale engine model... All in style of The King of 3D printed engine models Ericthepoolboy ( https://www.thingiverse.com/ericthepoolboy/about )
It is just a block, crankshaft, flywheel and pistons assembly for now. (I'm working on the rest of the engine)
There is still TONS of work to do... (many things can change for the final version - piston for sure, crank will look a bit more realistic too, block's flywheel side isn't finished...)
For assembly You will need:
6x (4 will work too) 6701 bearings
4x 623 bearings
6x M3x12/10mm SHCS screws for connecting rod bearing bridge
8x M3x16mm SHCS screws for crankshaft bearing bridges
8x M3x8mm SHCS screws for flywheel
3x M3x20mm SHCS screws as a piston pins
3x M3 jam nut for piston pin bolts
and I think:
6x M3 nut (jam and standard will work the same I think) for crank
3x M3x14 SHCS screws for crank
3x M3x16 SHCS screws for crank

Printed parts should be all 1 piece except:
Piston (3
