This is a stand I made to hold a pizza cutter and prevent scratches. I used 1.75mm PLA on an Adventurer 4 with no support in the configuration of the given file. 

I recommend 15-20% infill, since you don't need a super strong piece. Slightly under 2 m total filament when I made it with 20%. DO NOT RAFT OR BRIM, it may mess up the hole for the pizza cutter when you peel it.
