Portable Pi Zero

This shows the working pictures of a Gameboy knockoff I made with sheets of eighth inch plywood, a Raspberry Pi Zero (no WiFi), NES controller, and a 4.x" LCD screen. It works fine, but the case is flimsy and if you press in the middle at all the backlight cuts off and and you have to reboot it (since it's soldered in). My fiance told me should go in on one with me for Christmas but I can't seem to get into 3D modeling by myself. Most tutorials are for Windows apps or versions that look different. I didn't want to get one, print a bunch of Mario and Storm Trooper figures, get tired of it and never use it again. I've quit enough expensive projects/ventures in the past.
