Art card display rack

I wanted a way to display the Cards I have been making so I designed this shelf that is made so that you can print and snap together as many pieces as you want to create any length shelf you need. I also made end caps for a nice finished edge.The print profile has the settings set up to be able to print this on a smooth plate like I did, as shown in the picture.I printed this in PETG but I believe printing in PLA will work perfectly too, though I have not tested this in PLA. There is a .10mm tolerance on the pins & holes so that they fit together snuggly, this is by design so that the shelf pieces stay together and don't sag or come apart. and you will need to lay them on a flat surface and apply downward pressure until they snap together. There are no mounting holes since this is a small light and I wanted to avoid putting holes in my wall, I hung this up with the double sided tape command strips.
