End of Filament switch holder, 5 versions

thingiverse

I designed this switch holder because I grew tired of waiting for my spool to run out of filament. Like everyone, you want to use up all your filament before switching to a new spool. Using an extra endstop switch and creating a bracket was the solution. The idea behind it is that you mount the bracket about 30cm away from the extruder motor, after the last filament passes through the bracket, the switch closes the contact, and a buzzer makes some noise. Depending on your setup, you have enough time to activate the "filament change" mode before it's too late. If you're printing with a 1.2mm nozzle at high speed, better act fast! I made this for my CL-260 printer with a Bowden extruder and the 20/20 alloy profile in mind. Depending on where your spool is located, I created five versions of the bracket: one straight, two at 45 degrees, and two at 90 degrees.
