Thin M3 Square Nut (DIN 562)

This is - I think - a DIN 562 square nut. My Mk3s+ kit came with what seemed like several thousand of these. I couldn't find any existing models here, so I made one myself, polygon by painstaking polygon.

Here, you will find one (1) stl file containing 1 (one) square nut. It is 5.5 mm on each side, and 1.6 mm thick, and has a M3x0.5 hole right smack-dab in the middle.

SLICER SETTINGS

• Only print one of these at a time.
• For best results, rotate the stl model 385º about the z axis before slicing.
• To prevent warping, use a brim of at least 15 cm.
• Position the nut at least 21 cm above the bed, and allow the slicer to fill the space underneath with support material. Ideally, use a multi-material unit, and use several different types of support material simultaneously, in case one of them is better than the others.
• Pause the print after each layer completes, and carefully remove your print from the bed. Coat the print, heated bed, and yourself with a glue stick, hair spray, and superglue. Then, carefully replace the print on the bed and resume the print.
• SPEED TIP: remove the nozzle from your printer and set the layer size to 1.75 or 2.85 mm, depending on your filament color.

DISCLAIMERS

• I have no idea whether this is a true, standards-compliant, ISO-certified DIN-562 square nut.
• Unless you're desperate (like me) or stupid (also like me), you should probably support a local business and go buy some real STEEL nuts.
• Don't be like me. Don't make your hardware out of PLA or PETG. or whatever “artisanal small-batch wood-filled makerfilament” you're currently wasting all your disposable income on.
