Kệ/Hộp Đựng Danh Thiếp Gridfinity 2x2 (2 phiên bản)

Update (07.12.2023): I reworked these models to meet the correct Gridfinity Specs. I based the first version on this model: https://www.printables.com/de/model/399759-actually-parametric-gridfinity-base-grid-bins , which sadly does not use the correct parameters, what I realised way too late. The new version is based on this: https://www.printables.com/de/model/491528-actually-parametric-gridfinity-with-correct-dimens , with the correct specs. Thanks to schenkzoola for the remix. The new bin-models match both grid versions, so if You printed a grid from pcnc already, the new bins will still fit, they just have a bit wiggle (but not too bad).

Important: Print the new models with the corrected specs. If You really want the old ones, You can still download and print them, but they will only fit the grid from pcnc good. 

Business Card holder / storage Gridfinity 2x2.
One symmetric version, and one for maximum efficient storage. 

For cards with up to 55mm at the short side.

With the second version, You can e.g. store Your own cards in the big tray and cards from other people in the small - or use just both for Your own. :-)
