Sliders & rails¶

⚙️ Spec sheet →  —  visual schematic and metrics measured from a real rendered STL.

⚙️ Parts catalog →  —  this module is featured in the visual parts catalog.

Pure-Python port of BOSL2’s sliders.scad: a V-groove Slider and the matching Rail, both designed to 3-D print without support. Tune the printed fit with the slider’s slop.

class pybosl2.parts.sliders.Slider(l=30, w=10, h=10, base=10, wall=5, angle=30, slop=0.0, fn=None, fa=None, fs=None)[source]¶

Bases: object

V-groove slider (BOSL2 slider()).

The slider rides in a matching V-groove rail. Both print without support. slop tunes the printed fit.

Examples

A slider:

from pybosl2.parts.sliders import Slider
Slider(l=30, base=10, wall=4, slop=0.2).show()

Examples¶

These mirror the examples in BOSL2’s sliders.scad, rendered live through PythonSCAD. Examples that rely on BOSL2’s attachment/anchor system, or on features not in this port, are omitted.
