Bengal disc brakes pulley sealing plug for KMX trike

thingiverse

Improvements were made on a KMX Cobra recumbent trike; pulley openings, pointing upwards, collect dirt and water causing corrosion or freezing in winter. To solve this issue, a seal was created to fit better at the brake area. Instructions include printing, possibly drilling, placing it into the brake pulley hole as shown in the picture, then feeding the pulley through. For extra water resistance, some grease can be pressed into the space under the plug. The design has a larger hole than necessary due to printer shrinking small holes, fitting perfectly for the user. OpenSCAD source is provided for customization.
