can i print a 5mm thick cup to put my ospray ariel inside as i keep cracking the outer cover on them in my local bando.. will doing this cut down on connection to the vista neb pro ?

Dont miss to try a durable inexpensive dipole for your bando, sometimes they deliver a better image quality than omnidirectional ones and are more durable and inexpensive to replace either.

A tpu support like this can increase durability alot:

thankyou is the stl for your antenna available to download and print

I just puicked a random photo from picture search, i use some either.

What frame do you have?
If its popular, there might be some designs made for it, maybe for your ospray.
If not, you could correct a design to fit your frame or someone gently might design for you if you ask for it inhere :-)
