Robo3D Z Stabiliser

This is a spare/replacement Z stabiliser for the Robo3D. I decided to design my own as I didn't like the currently available designs. I tried to provide better support and strength without using a lot of additional filament.
Drill the stabiliser out to 8mm but start with the smallest drill bit you have that will increase the hole as trying to take too much out in one go is difficult and could result in breaking the stabiliser. Try to drill in short bursts to not heat the plastic up too much. Y
