I made this part for our Baby Jogger City Select pram, which had a missing button for adjusting the footrest.
V3 is the initial version. I printed it and works flawlessly.
V4 is 1.5mm shorter version, hopefully it is the same size as the original, but it is only slightly different from the V3 version, so I didn't printed it as the V3 worked perfectly.
I used PrusaSlicer with selective Support Enforcers, no need for full support.
