Oval conduit connector

I wanted to use some 20mm oval conduit as trunking but it doesn't seem like you can get connectors for joining them together. So I made a really simple model for joining them together. I have had one of these outside for a couple of years and apart from being dirty, is doing fine.for layer strength it would be better to do in PETG and more overlap would be better, which is why I have also put a tall profile but you can scale it to your needs.
