I recently released a new version of this. It looks much nicer. Is much easier to print and includes magnetic latching. Check it out.
I saw a box for CCG cards with a gearing system to raise the cards up. I thought it was quite nifty but at the same time, overly complex, requiring multiple metal pins. This is my own take on the concept.
Huge update - 05/12/17:
I have redesigned this significantly, with a much simpler construction method, two sizes for 60 and 100 card decks, and an embossed version for Magic: The Gathering players.
The following instructions are for the redesigned version.
To assemble, print the pieces you want. You need a cart, base, lid and pivot plates for each box. The components should already be in the best printing orientation in the STL file. Check the pivot plates slide into the base along the groove in each corner. Then, place the cart in between the lids, and the pivot plates onto each lid. Then just slide the entire top section into the base. The pivot plates should slide into the grooves at the bottom, and friction should keep the whole system together. If they're a bit loose, then just use some glue on the pivot plates when inserting them.
The following information and instructions are for the original version.
First, a little bit on the pivot plate components. The original design included pivot holes in the base print. However, there was usually insufficient flex to slip the lids into place, resulting in breakages. The pivot plates were developed to allow flex so that the lids could be put into place, and at the same time mean that only a tiny bit of reprinting was required if the plates broke.
To construct, print all the components. Then fit the pivot plates into the base (see photo). They should fit fairly flush with the side walls, so that the gears on the lids can fit past them. Because they've been printed with layers running along the long axis they should be able to fit in place and flex to accept the pivot pins on the lids. If they don't, then you could also place the entire system (lids, pivot plates and card cart) into the base all at once.
If you want to modify this and include a logo on box, then you can simply emboss a logo into the front, so long as it doesn't extend out past the pivot plates. The plastic thickness is 2.4mm.
Note: I'm still running an older lid design on my box - which is why there's a discrepancy between the lid and base when closed in the photos. The uploaded design has lid and base with the same width.
Note 2: I'll update this in the future for different deck sizes. If you want any particular size let me know.
Update 7/2/19 - fixed error in L slots in bottom of the 40 and 70mm base (unembossed).
