The Trek Allant+ 8S E-Bike has a rear fender that doesn't support accessory mounting like a trunk bag, etc. This is a Universal Bag mount for the Allant+ 8S. I suggest printing in PETG or PETG CF. Sized to fit a 245 x 245 build plate. You need to print 4 of the small brackets and get 8 M4 20MM bolts and washers.
I printed on both a Bambo Carbon (Final) and P1S (prototypes)
