BOSL2 VS dotSCAD

The BOSL2 equivalent is https://github.com/BelfrySCAD/BOSL2/wiki/CheatSheet

I used the BOSL2 library for the threads. Much easier that way!

https://www.thingiverse.com/thing:5905001 - Thanks to BOSL2, once I've defined a few constant, the entire source code is one (long) line:

I was heading down this path, but stumbled across this library that has a TON of really great functions: BOSL2. Lot's of useful stuff here and not just strings and math. I used format_fixed() to solve my problem. It doesn't seem to accept math functions in the call, but that is easily solved with an intermediate variable.

It won't be easy, but try using this: https://github.com/revarbat/BOSL2/wiki/beziers.scad

BOSL2 has a function for bending a polyhedron around a given radius but it's one of those functions that are super powerful but not very clear about how to use effectively (maybe that's just me).

If you're looking for examples of high quality openscad code, dotSCAD is pretty cool. nophead (old school reprap person and one of the openscad developers) has a parts library that I think is high quality.

Justin Lin passed away due to illness in 2022 at the age of 48.[0]

On December 22, 2022 OpenSCAD posted:

> Today's advent calendar door is a sad one. We'd like to commemorate Justin Lin, who passed away a while ago. In the OpenSCAD community he is best known for his #dotSCAD library. His designs always brought joy and amazement. Thank you, we will miss you.[1,2]

On October 11, 2022 dotSCAD v3.3 released — it was the last commit by JustinSDK on GitHub.[3]

https://github.com/JustinSDK/dotSCAD - as far as I can tell this is widely used

I synced your repo: https://github.com/JustinSDK/dotSCAD

// require https://github.com/JustinSDK/dotSCAD use use use n = 5; radius = 10; thickness = 1; geom = geom_icosahedron(radius); points = geom[0]; faces = geom[1]; for(f = faces) { triangle = [for(i = f) points[i]]; // subdivide the triangle triangles = tri_subdivide(triangle, n); points1 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * radius ]; points2 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * (radius - thickness) ]; ff = [for(i = [0:3:len(points1) - 3]) [i, i + 1, i + 2]]; color(rands(0, 1, 3)) sf_solidifyT(points1, points2, ff); }

If you are into OpenSCAD, grab this chap's work - https://github.com/JustinSDK/dotSCAD/tree/master/src and use his modules, they are rather good.

// use // a shape function from https://github.com/JustinSDK/dotSCAD // sq_outer = shape_square(size = 50, corner_r = 5); sq_outer = [[20, -25], [21.9471, -24.6053], [23.5868, -23.4835], [24.6602, -21.8118], [25, -20], [25, 20], [24.6053, 21.9471], [23.4835, 23.5868], [21.8118, 24.6602], [20, 25], [-20, 25], [-21.8118, 24.6602], [-23.4835, 23.5868], [-24.6053, 21.9471], [-25, 20], [-25, -20], [-24.6602, -21.8118], [-23.5868, -23.4835], [-21.9471, -24.6053], [-20, -25]]; // sq_inner = shape_square(size = 30, corner_r = 3); sq_inner = [[12, -15], [13.8551, -14.3577], [14.9158, -12.7057], [15, -12], [15, 12], [14.3577, 13.8551], [12.7057, 14.9158], [12, 15], [-12, 15], [-12.7057, 14.9158], [-14.3577, 13.8551], [-15, 12], [-15, -12], [-14.9158, -12.7057], [-13.8551, -14.3577], [-12, -15]]; polygon( points = concat(sq_outer, sq_inner), paths = [ [each [0:len(sq_outer) - 1]], [each [len(sq_outer):len(sq_outer)+ len(sq_inner) - 1]] ] );

path_extrude from https://github.com/JustinSDK/dotSCAD library. This kinda works.
