MPSM 40mm Case Expansion Blank

This case is made for easy customization to suit the builders needs. I built it because the psu I purchased was too long for the case and I didn't want to mount it externally. I designed the one on my mini to hold a 60mm fan. It can be imported into Tinkercad.com to build as you see fit. It goes along with https://www.thingiverse.com/thing:2335630 because I needed the extra space inside the case.
UPDATE* I added a standard sized expansion to the downloads. It works without the 25mm lift skirt.
