So I’m looking at heat shrink tubing to cover the wires of the nixies I got for my [belt gizmo](https://www.gbfans.com/wiki/equipment/uniform/calculator-circuit-board) build (using Nick-a-tron’s resin kit). I’m not an electronics guy, so I was hoping someone may be able to shed some light, here:

Is 3/64 heat shrink going to be tight enough for nixie and resistor wires??
