Simple holder that can hold a row of up to 6 or 7 chip plates.

Had the idea when printing out the calibration squares for HueForge. I now have this hanging above our drawing tablet so that I can more accurately color match with the filaments we have on hand.

This is the video link to the instructions on creating the TD chips.
 

Infill: The Chip Plates should be printed at 100% infill, any less than that and you won't even save any filament. You can get away with 20% on the backplate, but you'll see the infill patterns (which is kinda cool I guess?). I went ahead and did 20% and it's fine, but you may want to do 100% to ensure that it's sturdy.

Attaching: You will need to glue the chip plate to the back plate. I have created grooves so they should slot in pretty easily. A tiny dab of superglue should do it, but I'm a psychopath and laid a bead of gorilla glue along the entire channel (the earthquake may take my wall, but it won't take my chips).

Hanging: I didn't want to over-complicate it, so the backplate is simply flat. I used a couple of command strips to attach it to the wall and there doesn't appear to be any issues since the chips themselves are light. If you don't want to use command strips, I'm sure you can find some small profile wall bracket that would work just as well.
