Hall Endstop Mounts for Delta Printer

These are straight-forward endstop holders for Sainsmart Hall endstop sensors. I figured is was time to take them off the shelf and design holders to adapt them to a 2040 aluminum extrusion format for a 1M Delta Printer (https://github.com/electronlove/DeltaSpasm).

The carriage is a remix from Norwegian Creations magnetic ball joint carriage with the addition of a mounting point for magnets (https://www.norwegiancreations.com/2018/01/building-a-large-kossel-delta-printer-pt-7-design-files/)
