Soldering Iron Box

I have attached the FreeCAD project of the box, which is parameterized. I made the box at the maximum size of the bed of my Sovol SV06 ACE 220x220 mm printer, which is the parameter, the width of the box being at half of this parameter (110 mm) and the length is at the maximum height of the diagonal (260mm). The support elements inside the box are parameterized in size and position. These parameters also depend on the thickness you adopt for the walls, which can restrict the freedom to choose the dimensions of the supports, but they are quite resistant. I used the 3mm thickness for the walls, but I think you can use thicknesses from 1.6mm upwards without risking a faulty coupling between the lid and the box. For those who wish, they can intervene in the project to achieve the dimensions and utilities they need. I hope you like it. I used PETG, two layers for the walls and the triangle shaped filling. Good luck.
