PrintrBot Plus 2.1 M8 Z-Nut Adapter

cults3d

I recently received a PrintrBot Plus v2.1 and have changed the z-axis to use a M8 threaded rod instead of the ACME rod that it comes with. This allows it to use the same steps-per-mm as my PrintrBot Jr v1 which has been running an M8 rod for a year. However, the spot that captures the nut and stops it from rotating, effectively creating the Z-axis, isn't small enough to stop an M8 nut. That's where these objects come in. They are designed to fit in place of the original ACME nut with a cutout for a M8 nut to sit. I've put these on my printrbot and have printed two very detailed objects without issue.
