BOSL2 parts,
ported to Python and verified against the real app.
Every mechanical part here is a pure-Python port that builds real, watertight, 3-D-printable geometry through PythonSCAD. The featured modules carry a spec sheet with metrics measured straight off the exported STL.
The library
click a featured module for its spec sheetInvolute spur gears whose teeth are rack-carved with a real undercut, the way the current BOSL2 does it — plus helical, herringbone, rack, ring, bevel and worm.
Models of NEMA-standard stepper motors — body, plinth, shaft and mounting holes — plus the bolt-pattern mask to difference out of a mounting plate.
A print-in-place living-hinge mask, an interlocking knuckle hinge with a pin bore, and snap lock / socket connectors.
Shapes that connect two separately-printed parts: a tapered-or-straight dovetail joint — male tenon or female socket — and a press-and-click snap pin.
A ring hook: a rectangular mounting base that flares up and joins tangentially to a Y-axis cylinder — the ring — with a round, D-shaped or custom through-hole.
The five Platonic solids as watertight polyhedra — sized by circumradius, diameter, inradius or side. The dodecahedron is built as the dual of the icosahedron.
FDM-optimised walls that use less plastic and print without support: a cross-braced sparse wall, a corrugated wall, thick-edged thinning walls and triangles, and struts.
A routed bundle of round wires: hex-packed in cross-section and swept along a path whose corners are rounded, each wire coloured from a 17-entry table.
Watertight helical threads swept as one polyhedron; ISO / trapezoidal / acme / square / buttress.
Modular cube-truss segments, the trusses tiled from them (with end clips), L/T corners, diagonal supports, and the printed clip family.
Phillips, hex, Torx and Robertson driver-recess masks; subtract from a head to make the socket.
Standard cartridge models from a trade-size name — shielded (ZZ) or open, with the balls modelled rolling in the race.
LMxUU linear ball bearings that run along a rod, plus the pillow-block housings that clamp them to a plate with a teardrop bore and a screw.
The ball-and-socket segments of a modular "Loc-Line" style adjustable hose — a ball end, a socket end, or a full segment, for the 1/4", 1/2" and 3/4" sizes.
Standard soda-bottle threadings — a PCO-1810 / PCO-1881 neck and its matching cap.
A V-groove slider and its mating rail, both shaped to 3-D print without support.
