I printed the water Bottle Holder with normal PETG, so I improved the infill. But in generell very nice Print and until now it is doing a great job on my bike.
I’m not sure if you can get away without it. I used Prusa slicer’s tree supports and it worked great, though it did use a lot of plastic. Perhaps I’ll look into making the design more printable in the future
Had to file the holes down as was too short to be able to put both screws in. Also a lot of mess from the supports. but I’ve managed to get it to fit and will see how it goes
