Snap-Fit Raspberry Pi 4 Model B Case with holes for T-Nut for 3030 Rail

I have a Caribou and wanted to install a raspberry pi on the back of the z-axis. I loved this case for the Pi so i've made some holes to be able to use T-nuts to install it. I've used these T-Nuts. https://www.printables.com/model/117699-drop-in-t-nut-3030-profil-m3-m4-m5 For the second Model I've modified the T-Nut with a groove so you can keep the case aligned while screwing them. I've used these M3 screws with a small head from this kitt. I don't remember what length it was. https://www.amazon.co.uk/gp/product/B0B2543T68/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Thanks to the original makers fuchsr , Effixe , Malolo
