I really like the Festool / Tanos Systainer organizer boxes for storing hardware and especially parts for 3D printing projects! The bins include a slot for a paper label with a clear plastic cover, but I've found those to be a little hard to read from above because they're totally upright. I also prefer to use a P-Touch labeler to make my labels.
So, I made these little holders that fit snugly into the existing label slot and accommodate 9mm P-Touch tape. They are designed so that they do not interfere with the lid closure on the box, and they fit snugly enough that I'm able to use them as handles to help lift a bin out of the Systainer.
I've included a 3MF file with four variants with different angles: 30° (almost upright), 45°, 60°, and 90° (totally horizontal). I've also included STEP files at each of those angles, and the Fusion 360 model which has parameters for the angle as well as the tape size.
For my use, I like the 90° version. I find them to be easiest to read from above and through the clear lid of the Systainer. See the photos for examples at all four angles.
Printing
The dovetail on the little bins is quite tiny, so I printed these with the 0.25mm nozzle on the 0.15mm SPEED setting. I've used both PLA and PETG and both work well. In the photos, the black ones (30°, 45°, 60°) are printed in Prusament Jet Black PLA, and the 90° is in Prusament Anthracite PETG, which is a decent but not great color match for the Tanos Systainer Anthracite color.
They should be a snug fit. The tolerances are very tight, so depending on printer calibration you might need to tweak slightly. The bins have a small amount of draft so you'll probably notice that the holder fits more tightly as it slides into the slot. The top edge of the label holder should be flush with the top of the bin for the box to close properly.
If you don't have the 0.25mm nozzle, I think the 0.4mm nozzle will probably work fine if you use the 0.15mm layer height, or maybe the 0.2mm height. Some slight dimensional adjustment might be necessary with the larger nozzle.
For the 90° version only, they work best if you use a paint-on seam on the angled side. The 90° version in the 3MF has this seam painted on, and I've also included a screenshot that shows this. If you let the slicer put the seam in the default location, it just makes the face where the label goes a little uneven on the ends.
I made 94 of these and they fit perfectly into 93 of the 94 bins I used them with. The 94th bin had a little bit of extra plastic in the hole at the bottom of the label slot, where the tab passes through. I had to trim that extra plastic out.
