3D model description
Back in 2016, I broke the pedal on my folding bike. Yep, it was a folding pedal, and I could not find another one online to buy a replacement. So design one.
Well, the metal shaft was still OK, so it was only the plastic stuff that had disintegrated and I lost the spring in it.
Easy enough: just copy the other pedal, well, sort of. This is for #LIFEHACK3D . Even though most people won't have the need for a folding pedal, this hack saved a whole bicycle (unless I bought some non-folding pedals).
The pedal needs a spring (about 9-10mm OD by about 50mm long), to keep it locked in position when pedalling. I did create a plastic spring, but it really did not have the strength to be 100% reliable and was really hard to print using a filament machine.
The original design has 2 of 30mm long by 3mm diameter bolts, to lock in the bearing block into the frame. Slide the bearing block into the frame before putting in the bolts.
3D printing settings
Printed in ABS, and 50% fill (just to be sure, but probably could have used less) and increased wall thickness to 1.2mm (3 times nozzle diameter). Normal setting for everything else.
