Ender 3 S1 Filament Sensor Bracket

This Filament Sensor Bracket replaces the floppy stock one that's attached to the spool holder, allowing the use of custom spool holders. It secures to the Ender 3 S1 top rail with one M5x12 SHCS and a T-nut. 

Printed in the orientation shown in the rendering, using PLA with .028 layer height, tree supports, and 20% grid infill, it came out rough on the edges, but at 38 minutes to print, it functions as intended, so I can live with that (for now; I'll probably print a nicer one later.)
