About this model

This is a remix of the great electronic casing of c_wolsey! All credits go to c_wolsey. I found that the original casing was too small (lacking height) for my purpose. I wanted to insert a Raspberry Pi, a MOSFET module for the heatbed and a 4 port relay module and off course the Anet main board but struggled a lot with the original size of the casing. I ended up putting in a lot more, e.g. thicker cables, an optocoupler for the auto level sensor and a connector for the 220V mains. I noticed (during installing) that if you need to put modules higher or lower you would have to print the whole thing again. You counter that by cutting pillars or make mantle pillars (cilinders with a solid end caps with room for the screw; if you do this properly you can attach the cilinder pillars to the elect…
