I loved the design uploaded by user 2287298203. I just made it bigger and tweaked his two backing files to make it easier to hang on a wall. This will take about two and a half hours to complete, and is very beginner friendly.
This is just a very basic process of manufacturing the three seperate layers and then glueing them all together starting from the back panel with the eyes engraved, then the cut only panel and then the main panel. I also wiped mine with alcohol as the mdf can be a bit sticky after processing.
