Double sided fitting mount for PTFE tubing passthrough

I built a heated enclosure for my printer, but needed a good way to get the filament into the box. This part accepts two of [these](https://www.amazon.com/gp/product/B01IB81IHG/) which mate with [this](https://www.amazon.com/gp/product/B06XK3GZY6/).

My enclosure is built with acrylic walls. I used some automotive plastic adhesion promotor and I glued the fittings to the wall.
