M6 Nut With Large Integral Washer Trim Fastener Clip – 2017-2026 Tesla Model 3

3D-printed m6 nut with large integral washer trim fastener clip for the 2017-2026 Tesla Model 3, made to order as an affordable alternative to a discontinued or expensive original part.

About this part

Very simple mash-up of a nut and a washer because I needed them...

I used https://www.thingiverse.com/thing:311031 OpenSCAD ISO metric thread library by TrevM (thank you!) to create a metric 6mm-thread nut (10mm hex).

I used Designspark Mechanical to add an integral washer (flange) as I could not find a suitable nut or clip on Thingiverse (honourable mention; https://www.thingiverse.com/thing:3401133 by StuartL; close to what I needed.)

If you open the file in Designspark, you can easily 'pull' the outer surface to get a different flange diameter without affecting the nut size. I've created two sizes this way; large (25mm dia.) and small (18mm dia.) and have attached both files.

I've printed these with my Anycubic Delta but had smoother results with my Ender 3 - the Ender 3 is such a popular printer that I've also attached the gcode for this - try it if you're feeling lucky! - my printer is stock/unmodified and I'm using generic PLA filament.

If you're wondering what I needed an M6 nut with integral washer for - my Tesla Model 3 wheelarch liners were missing a number of fasteners from the factory. There were gaps where the liner didn't touch the wheelarch. The car has M6 threaded studs protruding from the sheet steel in the wheel well. The factory uses a thin plastic clip/washer that presses onto the stud. These are not very strong and don't fit very well, so an improved fastener is needed.

I could have used steel nuts, but they would probably corrode in the wheel well, plus I wanted a large washer to hold the fabric lining in place. If I'd used stainless steel nuts, they would stand out/need painting. Plastic nuts have a self-locking quality.

I am happy to report that the 3D-printed nuts can be screwed on with fingers, but a 10mm socket can also be used (same size as a standard bolt securing the lower corner of the liner).
