Bicycle Rear Rack Light Mount - Seat Post Adaptor

Adaptor to attach a bicycle rear light intended to mount to a seat post to a rear rack instead. This is useful if you carry items on the rack that would cover the light otherwise.

Versions

There are two versions depending on the standard hole distance of your rack: 50mm or 80mm

Additional parts required

• 2 x M5 12mm screw (maybe longer, depending on your rack)
• 2 x M5 locknut

Print settings

• print upright (for increased strength)
• material: PETG (to make it more resistant to the heat from the sun)
• supports: yes
• infill: 30%
• 0.2mm layer height 
• 0.4mm nozzle
   

Thanks

Thanks to Felix Müller for introducing me to 3D printing and helping me with the design.
