Description
This OpenSCAD file allows you to generate chain guards with an equally-spaced symmetrical pattern of screw bosses. Measure the distance between screws (centre-to-centre) and number of screws, then adjust the diameter/width of the rim to your preference. All measurements in millimetres.
Included is the model of guard I needed to generate - a 75mm 5-way design, for a Viking Trail E-Bike.
