Golf Ball Holding Jig for Drill Press

I made a bunch of bolas for a ladder golf game - so I had to drill many used golf balls. I designed and printed this little jig which goes into a small machine vise fixed on the drill press' table.

I used a centering jig like this to find the perfect centre of the golf balls:

I printed the jig from PLA - but PETG would have been the better choice because there's actually some visible wear after drilling 60 balls and not holding onto some of them perfectly tight 😁
