vial coupler resize

Great model, but when sizing it to fit if I got the top the right size the bottom would be loose and if I got the bottom right the top would be to tight. I down sized just the top ( the 3 fingers ) and it works better for me. I thought I would post this change in case someone has a similar issue. I used ABS because PLA was a little brittle when pushing onto vial and would break one of the fingers. Thank you for the design it really makes the pod changes much easier.
