I removed the holes that was needed to join two parts together on the V1. Now they just slot in to one another.

This soldering station can house most tools from AliExpress soldering kit.

I used PETG.

Extra perimeters on overhangs: ON.


Addon: 
top surface pattern Hilbert Curve.
0.3mm layers.
3 walls.
3 top/bottom layers.

For the soldering iron metal base to stay in place you need magnets. 20x10x3mm (actual size 19x9.25x2.5mm) 3 or 4 pcs.
