Added version 5 of the bottom, with a raised lip at one end of the slot for the soldering iron adaptor.

This helps ensure that the adaptor doesn't wobble inside the box.

If you already have v4 and is satisfied, no reason to print v5 :-)

I ordered some soldering iron tips for threaded inserts, so I can more easily and precisely insert brass threads in my 3D printed models.

The tip and the soldering iron adaptor arrived in a bag though, so I designed this organizer to store it and keep the tips more accessible.

I added text to the model so it will be easier to find the correct size.

Here is a link to the tool I use: ruthex 7x Soldering Tips/Melting Aid Set

Note: I uploaded the new v4 a day after the initial release, because I noticed one of the holes were not sized right.
Please re-download if you have v1.
