My parents have a nice and – quite – luxurious Camper. They bought it when it was a few years old but barely used. As usual my Dad started to make improvements immediately, all while complaining about “bad design and worse implementation”.
Quite soon he found out that the locking mechanism wasn’t an exception. When closing a lock there’s some stress on the lock housing, and it cracks after a while. Probably worsened because of a higher brittleness caused by UV or plastic ageing. New locks could be ordered, but for a hefty price tag.
Enter me and my brand new Ender 3 Pro 3D-printer. I made a copy with Fusion360 and many, many iterations later we have a functioning replacement. I tried to use PETG, but layer bonding wasn’t as strong as PLA.
