also the mendel 90 kit arrived last week, i am about 20% through a build, it is... challenging shall we say: around 200 nuts/bolts/screws which i really wasn't expecting! i'll likely be done by end of this week and can start experimenting. l.

If you do 3D modelling in scripted parametric openscad, I'm in with whatever is doable to help. Maths, formulas, etc, and anything that can be done up xmaxima + surfaces that can be done in K3DSurf surface generator, doing test prints etc.

i'm using pyopenscad, it auto-generates openscad files based on python classes: it is as weeird as the openscad language :)

okay! cool, i'd not heard of k3dsurf. awesome.

pyopenscad i believe is used to script up complex functions to generate objects surfaces because openscad is relatively simple language and doesn't have the giant features of python. Openscad is evolving - the latest version does tapered screw spirals. I made a tapered screw chuck type thing that is 1 inch and so strong it can take a spanner to tighten it and thread don't break. Unlike nylon screws. And this thing is done in PLA :( !
Anyway lots of designs released in openscad at thingiverse. Search for parametric designs - reduce chance of re-inventing wheel.

relatively simple... still incredibly awkward to understand: it's the "container" notation. which way round should it go? what should contain what? should an object be added to a union or a union added to an object?
also the language is not NP-complete so is, by definition, extremely limited for doing anything beyond what the designers of the language envisioned - and therefore forced onto its users - what it should be used for.
so the fact that the openscad language has a special feature for doing parametric screws has me alarmed, _not_ impressed. what's next to be added? what special extra feature? now fast-forward a decade and now the "relatively simple language" has become something that should be avoided at all costs.

do they have 3D spine surfaces yet, where the surface may be specified by a 2D array of 3D points and the intermediary points created to a required level of detail using bezier splines?
the answer should be *no* because it is a slippery slope to add such functionality to the base language.
