Mini Sanding Block - Flat bottom M4
thingiverse
Remake of thing https://www.thingiverse.com/thing:4441076 with flat bottom to not leave any marks from the bolt openings. In this remake I've changed to M4 hardware. The model is built with FDM printers in mind and doesn't require any supports. Need 2 x M4 Nuts and 2 x M4 bolts (16mm with hex head). ###### Clearance: Trough holes sized according to M4 normal fit (4.5mm). Clearance of 0.3mm for the bolt holder and nut holder on top of ISO max. 7mm and 8.1mm is used according to ISO. In the model 7.3mm and 8.4mm is used. The nut holder is 5mm so both normal and lock nut works. I would recommend using a normal.
