Nikon Coolscan 4000/5000 Full Roll Adapter V1

This is the V1 full spool adapter made for Nikon Coolscan 4000/5000. This was heavily inspired by mmsaxer1998, with some QOL changes.

• No need to use glue or adhesives to join both parts together
• The parting line in the middle is now covered, so dust can only enter from the entrance
• The adapter for the SA-21 was made to fit right after printing. The hinge part of the adapter was made thicker.

This is still V1, so I would love some input, so I can make changes! Would love to make changes and improve upon it!
