That does work, AppImages work just fine, but my cabling is both long and
slow, so its not as usefull as I thought it would be.
Using AppImages of both openscad and cura, I've made ball bearing
assemblies nearly 6" in diameter, stuffed with neasrly 100 crosman BB's
for balls, they work very well indeed. All to be part of a new design
of harmonic drive for some of my cnc controlled machines in the garage.
Clearly, I have too many expensive hobbies.
