Business Card Dispenser [read description]

Woohoo!  A new model!  :D

I made this model primarily in TinkerCad for the 2023 Business Card Holders contest [here].  I just barely finished before the contest closed. ^^"  The examples were printed on a Dremel Idea Builder 3d20.  No supports needed!  Assembly instructions are attached.

[UPDATE 17Jan2023]  “Base” part adjusted for better support and bigger business card sizes.  “Spring_needtwo” adjusted to hook in place better.  Taping or gluing the springs to “Base” may help springs remain in place.

[UPDATE 18Jan2023]  “Shell” part has been adjusted for better alignment.  This update only affected the “Shell” model.

NOTICE:  I have come to learn that PLA/plastic springs do lose their tension very quickly. The springs do work initially, but lose the needed rigidity in just a day or two, especially if business cards are left in dispenser overnight.  I am currently looking for a longer lasting solution and will update with my findings once I do.  Thanks so much for your patience.  I'm learning so much every day~ XP
