The model is fine and an easy print. I had size issues though.
My charger is 60.25mm x 26mm. This print in PLA measured 57.25mm x 26mm. Too Small. Could be shrinkage or could be that this was made for a different model charger (looks the same.) I'll modify and try again.
I used a skirt but it shouldn't be necessary if you aren't having bed adhesion problems.
