While far from his favorite toy, my cat interacts with the wiggle pickle often enough that it still gets steady use. Eventually one of the plastic bits broke so I made a replacement part for it.
The dimensions are close enough that it works. The screw post is probably too weak (especially in this print orientation), but even if that bit breaks off the screw is long enough to catch on the lower half.
I imagine this is only worth pursuing if you already have a printer and have this specific toy with this specific failure. 😅
