Sunlu S1 Dual Silica Box with Hygrometer Holder

Attention
if you want to mount the rear box with hygrometer holder you have to drill an additional hole in the lid

I did this as follows:

Hold the box to the lid from the inside, mark the hole position with a permanent marker and then make the opening with a hand drill

All parts can be printed without support

You need:

Front box
3x m3 heat insert
2x m3x8 screw
1x m3x10 screw (for the lid)
optional m3 nylon washer (for the lid)

Rear box
4x m3 heat insert
3x m3x8 screw
1x m3x10 screw (for the lid)
optional m3 nylon washer (for the lid)
