Cat collar magnet thing
thingiverse
To replace a lost collar magnet for a magnetic cat door, I initially purchased the door from Bunnings but found that Mutzi misplaced his collar before figuring out how to use it. Unfortunately, neither Bunnings nor Pet Warehouse had spare magnets. To create a new one, I printed two PLA pieces at .2mm layer height and inserted 7-5mm square magnets (available on dx.com). Finally, I applied super glue to both the joint and the magnets, ensuring a secure fit for collars approximately 11mm wide and 1.5mm thick.
