Desk Shelf inspired by IKEA-VATTENKAR

I based the build of the shelf to use the clamps from “hein”. Everything else is 100% hand designed by me. Local IKEA had shipping issues and VATTENKAR was out of stock until further notice, so I designed my own version. https://www.ikea.com/us/en/p/vattenkar-desktop-shelf-black-40541572/ The main shelf has to print in 2 parts because my 220x220mm build volume. You need to print 2, then mirror them and print another 2. It is designed to be held together by 3mmX40mm pins from Amazon: https://www.amazon.com/dp/B0FKGYVZZQ I've included the .3mf for my flashforge I used for the tower pieces. They have 4 walls, and printed at angles to strengthen. I have not be able to finish printing the shelves yet to take a good picture, so I'm including a 3D render as the main image. It was made in tinkercad, but I assembled the parts in blender for the image. All the fits are very tight by design so glue isn't necessarily needed. The shelf could use some superglue to make it leak-proof if you like, I am printing mine in PETG for that reason.
