T12 Soldering Tips Stand & Case

I once ordered a set of 10 different T12 soldering tips (from here or here) and had them laying around since then.

So the idea came up to design this stand and optional cover for it.

Prints without support. Also the cover!
It's recommended (probably required) to print the cover with a brim. An internal-only brim makes it prettier, but please make sure to fully remove it after printing.
I recommend to print the stand and the cover in different layer heigts to make them slide more smoothly.

I uploaded STLs as well as STEP files and my Fusion 360 project files. Feel free to create your own remix and please upload and reference it.

UPDATE

v13: Thanks to @Cliff_233210's advice I added a snapping feature and some grooves at the base to make it easier to grip. This is shown in the picture of the gold+black model I printed (the silver/glitter model is the original v10 without these updates).
