QUBD OneUp Bed Bearing Bracket

thingiverse

Updated Now including an integrated mount for a typical mechanical endstop. Also includes a bracket to capture a screw for adjusting the endstop. Also includes mounting braces for the heated basalt bed. These also significantly stiffen and straighten the bed. I was helping out a friend who has a QUBD OneUp with some assembly issues, so I started tinkering. One thing I noticed right away is that the standard method for attaching the bed linear bearings was very prone to allowing the bed to twist as it moved back and forth. Taking advantage of having a larger printer, I designed a part that used the lips created by the frame as a way to anchor a bracket in what should hopefully be perfect alignment for the linear bearings. This bracket is also a drop-in part requiring no altering of a OneUp printer. Simply push the bearings into the bracket and run zip ties as before. The results for me were impressive, as bed twist was completely eliminated. This is an updated model from what I installed on the printer with some very minor tweaks to the locating ridges for the linear bearings. I also added grooves on top to get slightly more clearance for the bed, as my previous version slightly rubbed.
