Chisel / Plane Honing / Sharpening Jig with MR106 bearings

thingiverse

The design looks good but I think the roller core could be improved by adding bearings or holes all the way through! I modified the original part in OpenSCAD to accommodate MR106 bearings, which are a simple push fit. The bracket would also benefit from rotating bolt holes so they don't print flat on top; however, that's a change for another time. Print two roller cores and then fabricate all the other parts from the original design. To assemble, use two M6x70 bolts and nylocs for the pivots, along with M5x20 nuts and washers for the clamp.
