BTT Smart Filament Sensor mounting Ender3 Topcrossbar 2020

thingiverse

I have the filament spoolfeeder on the right side of the printer attached to the wall. so I felt that the BTT filament sensor is better positioned on the top crossbar (a 2020 profile) and fed through 2 pulleys with bearings (other thingiverse prints) into the extruder. Printed enclosure part downside to the building plate with support filament ("BambuLabs Support W"). The bed-temperature was set to 40° and enclosure was kept open because of support-filament does not talke temperature over 40°C. I think the design can still be constructed in a more printable design with less need for supports and therefore included the parametric data (Fusion 360). I have used two M5 Hammerhead - T-nuts and two M5x8mm screws: 1) M5 Hammerhead - T-nuts: https://www.amazon.de/gp/product/B08GM37WHP/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 2) M5x8mm screws with rounded head: https://www.amazon.de/gp/product/B09BMWT3L1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
