There are things, like, say apple cores, that you can't always immediately dispose, but you don't want them lying around and exercise their free will. So I made this thing to limit their migration within the door pocket and isolate from whatever else may happen to be in the same compartment.
To save myself some trouble of taking measurements I used dimensions of the thing this is a remix of and also borrowed clip from there.
I printed it opening to the platform with no supports. Printer needs to be capable of bridging well for best results. I didn't master easily detachable supports, so I opted out of using any supports, but you know your printer better.
This was some 4 hours print for me at ~60mm/s using KISSLicer.
