Cable Gland Cover M20

I had cable gland attached to an outdoor junction box, but it will take some time before I have the cable to put through it. :-(

To solve this potential water inlet, I've created this cover, which can be screwed on top. It has a M22x15 thread.

The gland I used was produced by Plieger and has EAN: 8711238245867. The first image shows the gland and original "nut".

Printing material was PLA as it is not directly in the sun.
