For use with pets, luggage, school bags or as medical info tag. Or small storage container on your belt or keys. ID tag with (hidden) drawer. The drawer locks in place. By using the same color for the top layers of the drawer you can blend it in so it is less visible (when using the drawer upside down it is nearly invisible). By using contrasting collors you can let it stand out. There are 2 basic models:

The 5mm model for use with the 1.2mm drawer. Use this one for engravings. Use text as negative volume (for durability and strength) and switch filament at 1mm.
The 8mm model for using the 4.2mm tray. This drawer has a 3mm deep recess in which a paper note or other small items (microSD / pills) can be stored.

There are 2 ways of attachment:

The fixed attachment to slide over a collar / strap. This is 25mm wide and 4mm high, enough to slide over most collars or straps.
The flexible attachment using a few cm of TPU Filament. (no need to print TPU!) If you don't have any TPU filament at home yet, make sure you get a sample! You can do so much more than just print with this.. Insert the end of the TPU filament through the 1.8mm square hole. Tie a knot in the filament and pull it very tight! Cut off the remaining filament 2-3mm after the knot and pull the filament back so that the knot disappears into the larger hole. Repeat to make 2 loops. By making only one loop you can use it as a simple hanging tag. For more info and how to attach and use it this way (step-file shared and fast print sample fidget to test it yourself): TULAS: a universal hanging/strapping system

Printing: All parts can be printed without support or brim. I printed all at 0.2mm layer height with a nozzle of 0.4mm. All with standard settings. If the bridging sags too much, try to increase the speed with bridging or use the guide: Poor Bridging. The drawers have been given an intentional clearance of 0.6mm to compensate for slight sagging when bridging. *tips:

If it is still a tight fit, you can overrule the total height of a drawer in Z bij -0.2mm in the slicer. It will have no effect on the clamping.
The fixed cases can be scaled up in all directions. Don't forget to scale the drawer with the same scale. (I have added an example photo on a belt)

The engravings you can add with a free online STL text generator or the new Prusa Slicer. Use negative engravings of 2 layers and make sure to switch color at the right heigth if you want contrasting texts. For the 1.2mm drawer there is also the option to use the version with the recessed chamber and print raised text on the bottom (max 0.4mm) for sharp text. The raised engraving is then protected by the edge all around.
