I wanted to lift purge strands and carry them to the bin with one small tool, so I made a scraper with an integrated catch tray. I printed this version on my A1 in latte PLA, and the first physical test works well on my textured PEI plate.
The front edge is 0.20 mm thick, with a thicker ramp immediately behind it. The tray and side walls help collect the lifted strands. It prints as one piece, flat on the bed.

Use it on a cooled plate with a gentle shallow push. Carry level or slightly nose-up; the front is open. It is meant for purge strands and small liftable scraps, not prying strongly attached models. Long-term edge life still needs more use.
Design development and this write-up were AI-assisted. The demo is real continuous footage with light colour adjustment; the listing also includes the original print photos. I’d be interested in feedback from other plate and purge-line setups.
