TL;DR: Printed v2 with PETG and superglued it. No supports required.
After a flight, one of the wheels on this assembly was no longer there, but the bearing was still attached. The suitcase was a bit unbalanced, so I designed and printed a replacement. It slots in directly.
Design
There are 8 small slots, and three large slots. I found it easiest to align using the large slot that is flanked by the two smaller slots, and so I oriented the hole so that you can see through the openings to be able to aim correctly.
Versions
I designed two versions:
- v1 is a slightly tighter fit and requires quite a bit of force to put it on. It was also difficult to take out, but not impossible. Use this if you don't have superglue.
- v2 is the one I ended up using. The fit is slightly less tight (but still quite tight), but there's enough space for superglue to do its job.
Printing and assembly
I printed v2 above in PETG. No support required, and no extra parts required except for the superglue.
After supergluing the wheel, I let it sit overnight, and then rolled it around. Freestanding, there was a bit more resistance than the other wheels on the suitcase, but when rolling it on the ground, I didn't feel any difference, and it was stable. The brake also worked properly.
Disclaimers
So far, it has survived one flight and a trip across Japan. v2 ended up detaching somewhere. It might be better to use v1 with good glue.
(I found a replacement assembly can be found online for about 15 euro plus shipping.)
