FormBot T-Rex 2+ Drip Bucket for Silicone Wiper

thingiverse

I got completely sick of the brass wire brushes on the T-Rex 2+ getting completely gunked up and decided to redesign the drip buckets to instead use a strip of silicone for wiping the nozzle. Silicone blade I'm using is here: https://www.amazon.com/gp/product/B06Y6JNSV7 That's enough for 8-10 buckets total, so you won't run out for a long time, even if it wears out. Full Fusion 360 design is here: http://a360.co/2zMYRDi Once printed, just cut a piece of the silicone blade to length and slide it in from the back, then attach with the thumb screw from the original bucket. I oriented the blade so that the flat edge was facing into the bucket, so that it puts more resistance on the nozzle leaving then entering, which will knock oozing filament off better. I admit, the brush is probably better at cleaning off plastic that as gotten all over the nozzle itself, but I'm OCD about completely cleaning that off before starting a print, so this is meant more for knocking off drips during tool changes.
