A1 mini spool holder adapter

Designed this to fit around the A1 mini spool, to have the spool centered in place in order to prevent rolling undesirably.Inner diameter fits to the original spool and outer is truncated from 66mm to 45mm roughly.Per side, 2 pieces are in place, so to fit them together, you can either use the pins or the side clip (i find a single pin just works fine)Shells are also partially hollow to make it easier to hold for assembly or dissembly.
