I've opened my 3d printer and used it finally, during the in the 112 day Melbournce, Victoria, Australia lockdown. It is fun, but needs some fixes, but these can be printed by the printer itself due to clever designs.
I have a Monoprice Mini Select v1, the specs are here.
Spare extruder parts
Apparently the extruder clamp/ arm thing has been know to break on my printer, but here are the patterns for spare parts!
Drilling Free heat bed reroute with cable chain
There is another design fault on my printer were the routing of the heated bed wires rubs against things and needs eventually to be rerouted. This extremely clever design prints in several piece that snap together.
