    I built a friction drive for my bike with a load-bearing PLA motor mount (cheap crappy PLA, too), since I don’t have the equipment or ventilation for much else. With a bit of overengineering, it’s been doing great for almost a year now, despite all the heat and force thrown at it.

      That’s awesome to hear. Do you have any special techniques, like annealing? Maybe it’s just the consequence of my always buying bargain filament.

        Nothing too fancy! Mostly just designing a lot of thickness and buttressing into the part, and then slicing with thick walls, dense triangle infill, and an orientation that puts the layer lines perpendicular to the highest stresses.
