Sainsmart ProVer 3018 Extended Z Gantry-Redesign

thingiverse

I really liked the original version of this but I didn't like the design for the X axis lead screw and anti backlash. I had problems with the anti backlash nut staying in place so I redesigned my model to be the same as the original gantry. It uses the original anti backlash hardware so you don't need to purchase any additional anti backlash hardware. It seems to work much better. I also expanded the size of the holes for the bearings since mine seemed a little tight. I only expanded them by like 0.05 mm. Check out the original design summary for the parts that you will need (minus the anti backlash nut) https://www.thingiverse.com/thing:4793222
