About this project
A bench scraper with a lightened hex body, a serrated option on the edge, and a handle sized to your hand rather than to a catalogue.
Size
Blade width and length, handle length and width, body thickness and the handle corner radius. Handle length and width both have drag handles in the viewport, so you can size the grip by eye.
Blade
Edge thickness is the face that meets the print bed, so it comes off as sharp as your first layer is flat - 0.3 mm gives a genuinely thin edge.
Serrations are optional. Pitch sets the intended spacing and the model then divides the blade evenly, so the first and last tooth always land exactly on the ends rather than leaving a stub. The readout shows the tooth count and the real spacing it settled on.
Pattern
Hex holes through the body take weight out and give the thing some grip. Hole size, wall between holes, and an even frame wall around the whole outline - the pattern is clipped to the silhouette, so the border stays a constant thickness rather than cutting holes off mid-way.
The grid recomputes for whatever body you end up with. If you shrink the scraper past the point where a pattern fits, the design check says so instead of producing a blade full of half-holes.
Hang
Optional hole at the handle end, with position and radius.
While you dial it in
Readouts show the overall size, the blade edge with its actual serration, and the hex grid that fits - all three change as you move the sliders, so you can see the pattern reflow rather than guessing.
