Summary This is a remix of thing:39459 to perfectly fit the helloBEEprusa bed leveling nylocs. The dimensions are a bit too perfect, you may need to file the outside a little to avoid hitting the printer frame while the bed is moving. The values changed from the original SCAD are the following: knob_height = 5.2; knob_diameter = 8.0; knurl_count = 4; knurl_diameter = 0.7 knob_diameter pi / knurl_count; nut_width_flats = 5.50; I reuploaded the SCAD with little change to make this thing customizable but it is not working 100% (nut hexagon not subtracted), if you find out why it works on openSCAD but not in thingiverse please leave a comment. All the credits go to andygock for his excellent work. Print Settings Printer: helloBEEprusaRafts: Doesn't MatterSupports: Doesn't MatterResolution: 0.3mmInfill: 100%
