This is the arms for the spice rack I created. I used 3/8" wooden dowel from Lowes. Cut the dowel to length and mount using 3M command strips.
Printed on the Monoprice Maker Select Plus using Cura at 0.2, brim, with 15 infill.
The large version if for spice containers that are wider, although are the same height. I haven't tested them, so use with caution. This version may need stronger adhesion to the cabinet / door.
