Bike pedal to replace the broken stock one. Instead of spending 20 bucks to buy a pair from walmart, I decided to design and print one myself. First one printed in PLA with 40% honeycomb infill, snapped in half after about 2 months of daily commute due to cold weather. Second one printed in taulman 910 nylon with 35% honeycomb infill, incredibly strong and is working well. Should fit on all 1/2 inch thread Kent KZR pedals.
Turn fan off for nylon until the top layers, then turn on 10% fan for best surface finish.
