IR Filament Sensor Housing for Prusa Bondtech Mosquito extruder

thingiverse

This is a remix of wschadow's remix (https://www.thingiverse.com/thing:3581912) of the original Bondtech IR sensor add-on, designed specifically for the Bondtech BMG Mosquito hotend (https://www.bondtech.se/en/product/prusa-i3-mk3s-mosquito-extruder-upgrade). The wschadow and original Bondtech IR sensor add-on hole spacings aren't aligned with the BMG Mosquito body, which left the casing held on by just a single M2.5 screw. The original Bondtech adapter-printer part also had a big hole where the ball bearing used to be. Changes were made: 1) Moved the location of the M2.5 screw hole to match the corresponding hole in the Prusa Mosquito housing. 2) Added a slot for a second square M3 nut for better attachment of the housing cover. 3) Channeled out a slot under the smaller magnet to secure the housing body with an M3 screw to the Prusa Mosquito housing. 4) Modified the adapter-printer part to slot in a PTFE tube and minimize filament alignment issues. BOM: 1x M3 18mm screw 1x M3 12mm screw 2x stainless steel M3 10mm screws 1x M2.5 10mm screw (I used one from the Slice Engineering pack) 1x approximately 14mm length of 4mm PTFE tube (ID 2mm) 2x M3 square nuts The bondtech level arm and housing cover remain unchanged from wschadow's original design. Refer to that thing for the STL files (LeverBondTech.stl and SensorHousing-Cover.stl).
