Bike fork fenders / mudguard clamp (FreeCAD parametric)

Default is for 35.8mm fork diameter. This works well with SR SUNTOUR XCE28 fork. If you need another diameter, edit bar_d value in the spreadsheet. I printed it with PETG and 2 mm clamp_th thickness seems to be optimal for it, at least I broke 3 mm when tried to mount it on the fork. The part that deals with the bolt should be thicker and I set clamp_mount_th to 4 mm which seems to be strong enough, but you can set this value even higher if you prefer more weight and more reliability. clamp_hole_d is set to 4.3 mm for M4 bolts, you can change it to 5.4 mm if you use M5 bolts.
