T12 soldering tips box

I've designed and printed this box in order to store my t12 soldering tips in one place. I've also shared OpenSCAD source to enable customizing of the box. E.g., it's very simple to specify number of tips to store (tips_n). Length of the box is suitable for my longest tip (K-type).

STL files can be used to print this box for 6 tips.

It may be necessary to adjust size of the box's cap slightly in case it's very tight. The default adjustment (-0.2 mm) gives me good results printed on my printer using PETG plastic.

[upd] I updated .scad file in order to simplify its usage slightly. There are two logical "sections" at the bottom of the file: first of them is for preview and another one is for printing/exporting. I've also added comments there.
