P3 steel top improved

thingiverse

I've got a P3 steel V1 frame built, but that open top part and lack of radial support for leadscrews is a real problem. So, I just slapped in an F688ZZ ball bearing to give the leadscrews some support - simple, yet effective. As inventors often do, we take what works at home and make it more complicated when scaled up; try scaling this down by 10 and you'll find the right dimensions. P.S. I've also got a version for v2.1 frame users who want to give the ball bearing constraint a shot.
