Gridfinity (TS100 101) with heat inserts

I want to store my TS101 in my Gridfinity Storage box who has a high of 6u. To make the 3u solder iron holder stackable I have rotate it by 90°.My iron was sold with an non-slip cap so I add a small space to fit it.From the Heat Insert I kept only the adapter holder. The fit of the heat inserts are really snug. I use the adapter to push them in the first time.As I have enough space I added a slot for a replacement tip.
