About this 3D model

These bearing blocks will encase your linear bearings snugly and securely. Never again will you have to choose between damaging your rods, bearings, and plates by overtightening the bolts or leaving them too loose and having half the nuts spin off during superfast prints. >.< Updates from jcoffland's original: The orientation has changed; they are now set up to print flat. This means the weakest direction is no longer along the axis of the bolts, which in previous versions could cause them to delaminate and split. Because of the orientation change, the nut rebates now have lofted cuts so they can still be printed without support. The interfaces for the bearing holes and bolt holes have been modified so that the inside should not need filing. My bearings slid in perfectly straight off the printer -- snug but smooth. There is now a version for the dual head carriage as well as the single head.
