Hypercube Revolution Z axis holder

thingiverse

After 250 hours of printing, my z-axis bearings started slipping out of the holders. I thought it was a simple fix, so I designed a dual bearing holder that split in the center like the original and released it without testing first. When I installed the holder, I discovered that the bearings were working but not perfectly aligned. The linear rods also covered screws I wanted to adjust, making it necessary to have some slight play for the bearing to slide freely and square. To solve this problem, I added a clamp to the holders using 3mm threaded inserts like Scott used on other parts. I started from scratch and designed a new holder that holds the bearings in a stiff, full-length tube. The result is that the rods glide smoothly. All screws are now accessible for adjustment. The mounting wraps around the 2020 extrusion, holding the bed supports flat to prevent racking. Make sure you have enough space under the bed, as I added about 7mm of height. To assemble the new holder, slide the bearings in until they line up with the notch, which will put the clamp screw in the center of the bearing. Since I'm using a dual Z unit, I only use one bearing on each rod, so you can simply slide a single bearing to the center and then clamp it. https://www.banggood.com/100pcs-M3x5x5mm-Metric-Threaded-Brass-Knurl-Round-Insert-Nuts-p-1050182.html?rmmds=myorder&cur_warehouse=CN Print Settings
