Sparkplug box for Simson Isolator Spezial sparkplugs with space for 2 fuses.

Example Print on the pictures uses 0.12mm layer height for smoother stairs towards the top.

To close the box you need 2 O-Rings that are placed in the two grooves (I used 22mm O-rings, diameter of the box is 35mm so should be smaller than that but big enough to stretch around it)

Feel free to adjust the box to your needs
