Save space and put your Gasses on this Rack / Display. Printed with PLA on FDM is fine. Can be printed without leather glued on top of base ;) Print Base first, then the Baseplug, that fits into the Base. The Extender plug can be printed more times to make more shelfs with hooks. Only the Hook module must be glued into place. The 2 plug modules must be printed with support, in the top hole and under the Ext. bottom shaft.
