Parametrized jscad.app balcony door handle

Below link will open on https://jscad.app with the model:

I placed ten 1mm radius spheres at the corners of the model and then used (static) hull(…geometries) → {geom2|geom3} to get balcony handle with nice rounded edges in all directions.

Until now I used my JSCAD “edge()” function for 3D graph edges, here it is useful to easily cut the screw holes exactly between two arbitrary 3D points.

I had to cheat a bit, neither .js nor .jscad are allowed model extensions. So I mislabeled it .scad, clarifying at top:
$ head -3 balcony_door_handle.2.scad 
// This is a JSCAD file, open on https://jscad.app
//
const jscad = require('@jscad/modeling')
$

I thought I had no white PETG, I am curious what my wife will have to say about red print … she did not like the red print and I found some white PETG to print again (real speed 14fps nozzle camera video of my Prusa MINI+ — using input shaper made quite a difference to print speed before).
