These hooks add more hanging space alone, or chained together end to end with the included C-clip. Use multiple C-clips where more clearance is needed between layers.
I measured all the hanging holes on my utensils, and the holes were all over 5mm in diameter, and under 20mm deep, so I modeled based on those dimensions.
I printed in PETG with 10% gyroid infill. PLA would probably work, but with slightly higher infill, just keep in mind that something like a range hood can exceed 50°C.
All three pieces print pretty fast with 0.3mm layer heights at around 19 minutes per set, with no supports or brims. The C-clip is only needed to attach multiple hooks end to end.
To assemble one hook, take a main hook, and insert a cross hook through the long slot until it hits a retaining tab, push the cross hook straight down, push the cross hook C tail through the main hook C body, and pull one retaining tab through the main hook.
