compost shredder

This is a remake of https://www.thingiverse.com/thing:356580
I improved two parts, all other parts are from the original


This remix improves the strenth of the for_shaft_long with 4 M8 rods. I printed this part with 100% infill. The 4 rods helps that this part does not break so fast.
The other thing ive changed are the spacers. I use a Aluminium profile with sharp corners. The original spacers are designed for round corners. Therefore the original spacers does not fit on this profile. Dimensions are the same
