BTT Spring Thing

thingiverse

I had some (read: insurmountable) problems loading flexible TPU filament through the BTT Smart Sensor; the spring loaded rollers inside will not move and the filament just bunches up. So, this thing I created (my first Thing! - yay!) lets you push the rollers apart slightly making it easier to insert the filament. You'll need longer screws - M3x16 works. NOTE: This should probably be considered a work in progress. The items do not fit perfectly straight from the printer. I think due to tight tolerances, a bit of shrinking (or maybe I need to calibrate my printer) and a case of elephants foot I had to do quite a bit of small adjustments with knife and sand paper. Maybe if you print it a percent or three larger it will fit better. I'm not likely to print another one though, so you'll have to experiment. Sorry. :)
