So I was attempting to make the HBP Quick Leveler, but I was having trouble getting a clean print where the parts fit together.
So I put it aside.
But then I realized that the thumbscrews alone greatly improve the TOM's out of the box leveling setup.
This setup is working very well for me.
Print 8 of HBP_Thumb_Wheel STL, and press an M3 nut into each. Install as shown in the picture.
