This is a DIY project.
I used the base from this model:https://www.thingiverse.com/thing:4139419
Thanks to the author for sharing that.
I designed this extended fender to look as close to oem and provide good splash protection.
I printed this in ABS, the base separately, fender body separately and the 2 lateral supports separately.
The fender body I printed changed its shape a bit after removing it from the print bed making its radius smaller. This is ABS at work combined with a low infill percentage. I used a heat gun to gently bend it back to shape. Using a different material or different print settings can probably eliminate this problem.
The printing orientation is essential in obtaining a fender that has any chance of holding over time.
The parts are glued together with ABS glue (50g acetone + 8g abs mixed together).
The side supports are printed straight (no bends) for the best durability. I then briefly used a heat gun to bend the top and bottom parts (the slimmer parts) to the desired angles and glued the top part underneath the fender. I have 160mm rotors and had to bend the thicker part just a bit to clear the rotors properly. This should not be an issue for the factory 140mm rotors.
I also included a bigged variant for those with 3" tires. I have the stock 2.5" tires, so I did not print that.
I used 20% infill as this was more like a prototype, but I will use it for as long as it holds and the probably print one with 50% infill or so.
If you use other materials (like PETG) an epoxy plastic glue of sorts should do the job in fixing the parts together. Reiforcing the bond underneath the part is also recommended.
If you do print this, please post a make.
