Voron M4 BTT SFS 2

Bracket that mounts a BTT SFS 2.0 to a Voron M4 on an Ender3 v2 for clean routing and better reliability.

This bracket adapts the BTT SFS 2.0 filament sensor to the Voron M4 extruder on an Ender3 v2, giving you a clean, stable mounting point that avoids hacks and zip-tie fixes. Designed for consistent filament detection and smoother cable management, it installs fast and fits tight.

Ideal for anyone upgrading an Ender3 v2 with Voron hardware or looking to reduce wasted prints caused by runout failures.
