My first proper attempt at designing something in Fusion 360 I'm not ashamed to share.

Intention is that 3 PLA tags are printed and then snapped into a TPU(rubber) holder.

In the presumed 3-tag sandwich, centre tag is left solid for whatever colour you want your text to be. On outer tags you can punch through text of whatever you want the tag to read on each side and choose a nice contrasting colour.
Unfortunately TinkerCAD doesn't seem to support a 'stencil' font (so parts of the letters would fall out - but you could always glue them in, if you want to keep the project simple).
360 links below should allow you to modify your text using Stencil font and export your own STL.

As I said at the top.
This is the first thing I've ever uploaded to Thingiverse and would be over the moon if anybody even collected this. If there's any file/anything preventing you making this, please shout and I'll do whatever I can to help.
