I needed a DIN case that would fit an Arduino UNO, LCD, Arduino shield and a Solid state relay. So I took this https://www.thingiverse.com/thing:3402441 one and altered it a bit.

Things changed:

• Moved Arduino to right to make room for shield
• Made it bigger (7 units)
• Removed fan
• Added mounting for Solid state relay
• Moved cable in
• Other small improvements
