Replacement Treadmill Safety Key Clip

thingiverse

The safety key clip on my Nordictrack treadmill malfunctioned, likely due to wear and tear. To enhance durability, I reprinted a replacement with increased thickness at the fractured point compared to the original version. Following a year of usage, the initial design broke again; thus, I upgraded it further. For printing, I adopted a vertical orientation (as per the diagram) with 75% infill, support enabled, two shell layers, and a layer height of 0.30 mm.
