Hex Nut Stress Relieving Washer

SummaryThis is a very simple but useful stress spreading washer designed for M3 Nuts and Bolts. The printed washer spreads the stress from the nut and machine screw, reducing the tendency to crack acrylic and other brittle plastics. It also reduce the tendency of the hardware to dig in and crush wood panel. Also the plastic improves the friction of the nut to hold it still while tightening the machine screw. InstructionsPrint this solid or pretty much solid. Play with parameters in the Open SCAD file, to adjust the fit, diameter, thickness, etc. You can also change the number of washers in the array, so that with a single print you can have as many as you need. It also adds a simple wipe object in the corner to prevent crap on the edge of the first washer in the array. These print fast, and are very useful. Print a bunch to have handy.
