Roller Shutter Stopper

This is a replacement stop for rolling blinds or shutters. The design does not require an additional nut and uses a standard pitch M6 bolt. The stopper is approximately 36 mm tall with a base radius of 20 mm.
I created this model after failing to find a replacement that met all my requirements. It’s very easy to print, the bolt threads smoothly, and no extra nut is needed. Use an M6 bolt with a maximum length of 30 mm. Two different washers are included in the design but are optional. Old bolts can be reused, but be careful as some stops use non-standard bolts with a larger pitch.
The thread and one washer were generated using the excellent parametric thread and screw generators by user Koolm:
