I got fed up with not being able to find one of those silly little SMA aerials for testing a tracker, so I knocked this up in TinkerCAD. It's so useful so often to have a 3D printer.
@jonobennett And then Tennis.
@cabebedlam It's not the kind of watch that anyone sensible would go swimming in :) so I'm not looking for it to be 100% waterproof.
I've tried printing in PLA and it printed well. I got the corner radius wrong and I need to tweak it a bit but it's close. I'll order some TPU.
@peter Thanks Peter. Old one was 0.5mm square section. I bought a pack of assorted watch o-rings but, being round, they don't want to stay in the groove.
I'll try it in PLA and if it fits I'll order some TPU.
I have an 80's Casio calculator watch with broken o-ring, odd shape and not available anymore. What are my chances of printing something workable in TPU?
@angrysmiley Hah yes, I saw that posted somewhere a few days ago!
