Hey everyone, I reprinted my guard bracket with ABS, and the shield fits as expected. I will more than likely need to trim some of the edges that bump the wind screen, but preliminary testing show promise even up to 65 mph.
I have one really big question about plastics that I hope someone can help with. Many of you are more experienced with different kind of filaments than me :).
This design uses a tightly measured ring with a bolt and nut clamping mechanism to secure the bracket to the bar end weight (you can see it in the photos where it attaches to the bike). Does anyone know if ABS, PLA, PETG or something different would be the LEAST abrasive to the paint coating on the metal bar-ends? I originally printed this in TPU, thinking that the flexible filament would do the least harm, but the weight of the shield caused everything to droop and bend too far. ABS seems sturdy enough to handle the wind, but I dont want to scratch the crap out of my bar-ends with the way the plastic attaches.
Will I be ok with PETG? should I CAD the bracket a bit bigger and slip a sheet of TPU in between the end weight and the ABS/PLA/PETG bracket mount? Is there another magical soft but rigid filament out there?
Any help or insight would be super appreciated! I would love to avoid scratches and rust! thanks!
