This is a gasket to help better seal your V-Core 3.1 with enclosure 2.0. The size of the round opening will depend on your exact umbilical size and how many cables you have. This is sized for a USB cable for a toolboard, a second USB cable for beacon, 2x 18 gauge power wires, and 4x 22 gauge wires for the 4028 fan. I included the step file so you can make the hole bigger if needed for bigger umbilicals.
It is a tight fit to get this in place and needs to be bent/smooshed a little to slot into the proper location (at which point it should fit appropriately). Print in flexible TPU with 2 walls, 2 top/bottom layers, and a spare infill (cubic at like 10-15% worked well for me). Hope this helps seal up your enclosure better!
