This is a replacement clip for Sterilite storage bins. I used PLA and that seems to be working well for the few weeks I've used it, but I imagine long term durability will be increased by PETG. If it's too tight, try scaling it up by 1 or 2%.

I'm using the Prusa Mini, which isn't in the list. I used 100% infill for durability, but it's thin enough there's not much room for infill anyway. I printed it with the flat side down. The pegs need support, but I blocked the supports that prusa slicer wanted to put under the lip and it was fine with PLA.
