The detail that caught me off guard is the blade itself: the maker built a printed body around the metal scraper blade that comes with a Bambu Lab printer. One end helps lift prints off the build plate, and the opposite end cuts filament, which the maker positions as a backup for when no dedicated cutter is at hand.
Assembly reads as deliberate. The grey housing sections are joined first, then the orange endcap goes in. A compliant printed spring and the slider tab are fitted into the translucent blade carrier, after which a metal utility blade is positioned on the carrier and held by two small hex screws, tightened with a thin hex driver. Once the carrier slides into the housing, the slider tab operates the tool. A final touch is paracord threaded through a corner hole, knotted and trimmed with flush cutters.
The case hides the metal blade when the tool sits unused, and the sliding mechanism was cycled to show both locking and deploying. The open question for me is plate safety: the maker says the angled blade edge should not contact the build plate at the intended angle, and reports using it with a P1S and an A1 without issues. That is the one thing I would keep an eye on with any metal scraper.
