Tupperware Spice Rack

I printed a new spice holder for the Tupperware spice containers.Our spice holder got brittle because it's a few years old.So i decided to 3d model the holder and print it via a 3d printer.The holder consist of single parts, which are slided onto the rail. If one part break, you just need to print that one new and can just slide it on the rail for an easy exchange.On both sides of the rail there is an extra part which is screwed into the rail. This parts stops the single holders to slide of the rail.The rail is mounted on the wall with 2 Screws. The rail is also splitted in two parts (only reason for that is the printbed from the printer)
