As most of my designs this one was done to fill a need. The shelf in the freezer of my Keystone travel trailer was broken. It is no longer available so I decided to print one. Its been an interesting journey. I did have another shelf that fit but it was difficult to scan so I had to take measurements and use them to design the shelf.
No special print instructions. It printed great with PLA + , use the 3mf files provided and the supports should snap right off.
