About this 3D model

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.
