Took the original design from sebasgot and as it wouldn't have fit my nozzles, they have a longer threaded part, I made the slots ~2.5mm longer. While I was at it I also shrank the width of the box by around 10mm. This did cost me one nozzle location but 11 is enough for me anyhow

As I plan to have the same wallets for different nozzle diameters I also made front panels for 0.6mm, 0.8mm nozzles and a blank one. Just for convenience I also added the STL-files for the part I didn't modify, the lever. All files are oriented the way I printed them. Tray and sleeve with 0.3mm resolution, lever with 0.15mm and front panels with 0.2mm, and all with adaptive layers in PLA on my Anycubic i3 Mega S. The shell I printed with brim, the rest with skirt only. Only the lever was printed with support.

To be honest, I like this design better than my own......

And before you ask: such stuff I print with left overs or colors hardly used which leads to surprising color combinations.

Hint: if the tray is to lose in the sleeve and tends to fall out with gravity (had that on my second print) just put some superglue on the side of the tray and let it completely dry. That's usually enough to get sufficient friction.

Edit: with the front panel glued in there is no need to have the ejection lever. The tray can be easily puled out by just pulling at the front. I added the two -no-lever.stl files for that. Bonus is that it now will hold 12 nozzles again.
