The case which holds a power distribution block in my truck cracked and broken into pieces due to vibration overtime. So instead of buying a new one, I just created a new case to hold it securely. The original case always felt brittle so I knew this day was coming. Tossing is on Thingiverse in the event someone has the same issue. I do not have a need for a top for this, so I didn't add one, but it could easily be added.I printed with infill 100% shells 2 layer height: 0.2mm
