Ok up to Mk3 now beefed up some areas and added some under hang to allow easier removal from bed, I broke one of the last ones getting it off. Updated with Mk2 versions. set the A version with pass through holes and B with thread taking holes. Recessed the bearing screw as it is hard to adjust the length screw past it. It will need 12mm screws now. adjustable filament reel roller. I have a number of different makes of filament and all seem to be different sizes so I needed an adjustable roller for them. Screws are M4 X 40mm the bearings are 4 x 10 x 4 with M4 washers about 1mm thick and held in with M4 X 16mm allen bolts. Instructions printed in PLA at 0.2 layer 30% infil. The bearing support holes are all tapped to M4. half the holes are drilled out to 4mm and half are tapped to M4
