USB soldering iron box organizer

I bought an USB soldering iron for a less than 7€ and didn't have big expectations but it works well for small works.
So, I'm happy with it and the manufacture is surprisingly good for the low price...
Except the box organizer that looks like what you have in cheap cookies box!
So, I redraw mine with an improvement: The ability to let the tip on the iron (it's designed not to let it touch the box).

It's easy to print (no support needed) but a bit long (about 6-7 hours on my old Alfawise U30).
Perfect fit with the case. Used: Basic cheap PETG, layer 0.3.

I've started to draw in several parts to optimize it but gave up, as it will take about the same time and have to glue / add screws on it, so not so good at the end I suppose. The FreeCAD is given so, feel free to improve it if you have time (You can save space under for example, if you need to store more accessories in the box).
