Pi 4 server + HDD enclosure

I created a Raspberry Pi 4 server with a HDD directly link to it. I wanted to have a specific enclosure to get everything inside so I designed this one. It's printable in 3 differents parts to allow you to place the HDD in the bottom one, them the raspberry pi 4 on the middle one then close the top with the last one.

It's designed for a 2.5'' HDD of Western Digital but I thing it can work with any compatible disk. Same for the raspberry pi 4.

I'm willing to modify it thanks to your feedback.

Note : Only the middle part needs supports for the raspberry ties, not for each holes.
