Previously, I floated the idea that frames can/could/should be printed cheaply using an FDM/FFF printer with PLA0 and then strengthened using one or more of a variety of techniques- which would yield an inexpensive, fully compostable/disposable skate part, to be manufactured on demand anywhere by anyone with electricity and a basic printer.

I thought this was going to be difficult, would require strength-adding design compromises and might take a lot of trial and error to make work for more than just a session or two, despite PLA's rigidity and technically ideal mechanical properties ...
