Customizable Filament Sensor

This is hopefully the last filament sensor you'll ever need (for switches anyway). I looked at a bunch, but every one I printed would not fit my switch. They also all seemed to fit different switches... so enter the customizable one. I'm using these, https://www.aliexpress.com/item/MYLB-10-Pcs-AC-125V-1A-SPDT-1NO-1NC-Momentary-Long-Hinge-Lever-Micro-Switch/32745688469.html, though the whole point is it doesn't matter any more. Just measure yours and enter the numbers.

Description

Customizable, so specify the size of your filament and switch and how much space you want for wiring and you're ready.

Measuring the screw holes is probably the most annoying part. Be sure you're calculating the center of the screw hole. To do this, I used my caliper to first measure the screw hole width and depth (mine were not perfect circles), and then I measured the distance from the edge of the hole to the lower left corner of the switch. Lower-left may be arbitrary but if you're using a filament flange and your screws aren't symmetrical it will matter. You must enter both X and Y for both screws (all switches I've seen have 2 screw holes, if you have more or less the thing will have to be updated).

I printed in PLA+ and ABS. The design is relatively tolerant, though the cylindrical filament flanges may get a little messy. You could add supports if you care a lot.
