Putting together the Anet A8.. One quickly realizes there is a lot left to be desired... I tried about 2 different X belt builds / things from thingiverse .. I wrestle with them a bit but they were to tight.. or... I just need smaller fingers. Maybe the 2017 build belts are fatter.. don't know.
I put this build together with some extra space to work with... really 2 screws is all you need
PLA / 25% fill / No Supports
Tip: Instead of building a belt tensioner.. remove x motor bolts..cept one.. leave it loose to keep motor attached.. pull motor towards center...attach belts to x belt anchor (not bolted) pull motor back in place.. bolt it up...bolt up x belt anchor
