This is a (somewhat poorly) remixed version of 3D_Lover's Tiny Mac. This has been modified to accept a Raspberry Pi 4 and to use a different screen (this one specifically https://www.aliexpress.com/item/32895077923.html).

This remixed with a combination of Meshmixer, Blender and 3D Builder, and I printed my version on an Ender 3.

Note that when printing supports, it will be quite difficult to remove them.
