Snapmaker 2.0 3D Printed Head Internals & simple cooling upgrade

[@asdf35750]

The real problem with Snapmaker cutting the extruder teeth into the motor shaft is that extruder gears do wear out, and when that happens the ENTIRE MOTOR has to be replaced.

luckily this things are modular, but i agree same thing the cooling fan needs a better upgrade something abit more beefier.

mine has worn down and I can't find replacements for the motor. seems you have to buy an entirely new 3d printing module to replace the gear.
