Dial Indicator Bed Leveler for QU-BD TwoUp 3D Printer

Recently we designed a dial indicator holder for the QU-BD TwoUp! 3D to help with bed alignment and improved prints.  We printed this in ABS (you could also print in PLA) with thick shells, 30% infill with supports.  This mount is designed to hold a standard dial indicator such as VkTech which can be purchased from Amazon for around 10 bucks or so…

So you have a OneUp! or TwoUp! with those melamine bearing retain clips which either break or come lose?  While here is my answer to that problem as simply print some new ones.  If you look back a I did a post on building them, however in this video you see them installed with several of my other tricks too!  So if your having a love / hate relationship with your bearings!  You need to watch this video!

Q3D TwoUp 3D Printer Kit Bearing Retainer

This is a replacement Bearing Retainer for Q3D TwoUp (and OneUp) LM8LUU as the melamine ones tend to break or fail.  As there should be printed with a think shell as well as about a 30% in fill which will make them rather solid.  As the ABS (the preferred material)  tends to spread at the bottom layers, you will likely need to clean out the ridges inside with a hobby knife and bearing should then “snap” (i.e. make a snapping sound as they engage) in holder.  Also when tightening down, would also suggest using a cross pattern being top left, to bottom right, back to bottom left and finishing at top right so pressure is applied evenly to the holder.
