Mount for bike fender model SKS Shockboard

thingiverse

When I got my front fork replaced I lost the mount for my fender. An accessory mount would cost 2/3 of the whole fender so I decided to make one. The mount works by inserting the cylinder up into the cavity of the fork then tightening the bolt to cause the cone to spread the arms of the cylinder to become become lodged by friction in the cavity. The bolt also holds the flat piece onto which the fender slides and locks with teeth. Supports needed for the 'mount' (flat) piece only. The orientation on the print bed for the three pieces is as shown in the files. Specifically, I found that printing the 'mount' was best on its end. The bolt is 4mm diameter 35mm long. Longer would work too. Washer diameter 10mm. Nut diameter 8mm. If you need to buy the bolt, washer and nut maybe print the parts first and take them with you to the store. Or buy them first and resize the parts in OpenSCAD to fit what you bought. The cylinder that fits inside the front fork is 20mm diameter. Your front fork may require a different diameter. If so, you need to reprogram the model using OpenSCAD. The .scad files are included here. I'm willing to answer questions or fix issues people find with the parts. Just post a comment. Update 2019-04-16: I found that the nut end of the spreader was weak and has cracked so I made the cone wider at that end to strengthen it. Files are updated.
