Just a simple spice rack for a wall or door, i printed mine from ABS for strength at 0.2mm layers.
Uses 6mm stainless steel rod, they just tap in firmly with a soft hammer
I used 0-5mm hollow wall anchors from bunnings to attach to my pantry door https://www.bunnings.com.au/ramset-5mm-hollow-wall-anchor-4-pack_p2265436

theres a small version upto 42mm diameter jars and large up to 67mm diameter jars

if you print with abs, remember to scale. 3DFillies white needs printing at 100.74% to be spot on
