Brake Clamp w Snap Groove for Large Hub Spools

Remix of the original Awesome spool clamp by DJ_Designs.  Thanks!

Tested on the Bambu Lab A1 spool holder. Compatible with many common filament spools including Creality plastic spools.

Changes include:
• Added internal groove to improve grip
• Added extended version for larger spool diameters
• Minor geometry adjustments for easier snap-on installation

I started using this on my A1 to add just a touch of tension to the spool to keep the filament from loosening

Especially with spools that are almost finished and light

It clips on the end cap of the holder and also prevents the spool from wobbling too much during fast and repeat motion

The purpose of adding the groove is to align it when installing for a light touch for braking

and to prevent the clip from sliding off during heavy use

The purpose of making in longer is for spools with large hubs like the Creality plastic spools

Again for tension, wobbling and to prevent spools like that from actually riding off the holder

(learned that lesson the hard way)

Hope it helps
