Metered 4-way switch box with 45º view

Needed a metered box long enough to contain a 50 Amp shunt for the V/A meter. The meter was hard to view in its former rectangular project box so I thought a 45º angle would work better.

The tolerances are far worse when printing holes vertically. I used a Dremel tool to round them out but it wasn't enough and some of the layers near the switches are delaminating. But it's managing to stay together. The connecting lip for the lid I made too thing and it broke off easily along the angled top.
