I designed this cover to fit over a FOTEH SSR-40 I purchased on Amazon.
The unit I received is 60mm in length and 45mm in width.
The cover clicks on and stays secure by itself.
The one I've printed is PETG but I believe it can be printed in any material you like.
No support is needed.
If you print it share here the result in the make section.
Enjoy.
