If Z-corp had lathed in a 2mm x 5mm deep notch into the spreader, they could have eliminated the need for the snowplows, and the mess of powder on each side of the print box. ![]() I'm thinking about 3D-printing some less-terrible replacements. The 'snowplows' on the sides are held on to the side of the bin by (pretty weak) magnets, and I think they are too short to do a good job. There is no metal scraper, only the roller. (At a 2x slow-mo, I counted 2 revolutions per second, so that's about 4 real revolutions per second, or 240 RPM, calling it 250 RPM) ![]() The freeware is limited to module 0.75, 1, 1.5, 2, 2.5, 3 as well as pitch. There is a rolling spreader, 19mm in diameter, that spins at approx 250 RPM. ZPRINT Gearprinter is a software for creating STL files from involute spur gears. ![]()
