These are much deeper than authentic command hooks. To mount them, I use the extra adhesive strips that come with a pack of hooks. The model was designed by user ES0602 who made it freely available here on Thingiverse. These hooks were printed with 100% infill for super strength (that’s probably overkill). I got good results using 0.16mm layer height, but an even smaller layer height would make sure the inside of the hook is smooth.
