I printed 4 of these on A1 mini and it's working really well. All 4 are using Bambu PETG Basic and it prints almost perfect except some of the layers from the middle part become separated. It could be that my PETG is too wet (it's about 45% humidity here in the room) thus a word of warning to make sure you dry it out if you can. But otherwise - great model.

Can't be more perfect than this. Fits well and does not hinder usage on AMS lite in any way.

Printed perfectly and spring is just the right amount of squishy. But sadly it does not quite fit on the 27GN950 which has like 4-5mm ticker top bezel. I tried to extend it on my own but it's hard without the actual design file.

This printed fantastic and it stays properly in place despite the sometime too-jerky movements of the print head. It does not slide down on its own.
