ZWO EAF 15mm Spacer

Not sure how many more words I can use to describe it. I was mounting a ZWO EAF autofocuser to my AT60ED and needed a spacer. Went with 15mm for no reason other than it felt about right and let me use a couple M3x30 bolts to attach the EAF to the bracket without bottoming out inside the EAF. 

Printed with PETG / 15% infill, shouldn't make much difference whatever you choose for your tastes.
