Case for DC-DC converter with barrel jack

thingiverse

This remix adds a space for a DC barrel jack connector, fits most generic ones at 9mm wide. The lid has a tab that holds the connector down. Both this tab and the body of the connector have slanted walls connecting them to the bottom to avoid the need for supports in those tight spaces. I also included the Sketchup file in which I made my modifications, so you can make your own version.
