Box Insert for Tokens and Stuff (BITS): 315mm Internal

I am moving board game miniatures onto shelves and so am consolidating each game and all of its expansions into a single box.  To do this, I've created this generic box insert system, BITS, the Box Insert for Tokens and Stuff!

This BITS is sized for a box with 315mm internal measurements, such as Bloodborne or Death May Die.  The general logic behind these components is to treat the box as four quadrants and to make card and token holders sized to fill up a quadrant.  That way, each quadrant can be customized based on the needs of the particular game (like how many tokens or cards it has or any special storage needs).  My intent is to make derivatives of this project for game-specific components that "complete the system" for each game.

In this main BITS project, you'll find card holders sized for Standard, Medium, Small, and Mini sleeved cards.  There are both "stoppers" and "dividers" for each card size.  The Stopper is a compliant mechanism that snaps into the square holes in the card holder to stop the cards from flopping around if there aren't enough to fill the holder.  The dividers are extremely thin card dividers with tiny ridges along the top to help you align labels.

The Card Holders are designed to be able to be printed twice, with one acting as a base and the other as a lid.  There are tiny slots for four 1x3mm magnets on each half; these magnets are just strong enough to keep the lid closed.  If you want to use these magnets, ensure that you slice it so that there are at least 2 layers of plastic above them (there should be .3mm, so make sure that those layers are something that divides evenly into .3).  I printed a few of them with .2mm layers and the slots were too loose, making it difficult to get the magnets to stay inside.

There are also token holders that are sized to both compliment the card holders and to "stand alone" taking up half of their quadrant.  For example, if you're printing the 101mm wide Standard card holder, you can print the narrowest token holder (a full stack of 3 of them will be as tall as the Card Holder) and the two of them, side-by-side, will fill a quadrant.  If you print the 55mm wide Mini card holder, then the widest token holder will compliment it.  You get the picture!

Each Token Holder size has a lid that can snap onto it; I only bother putting lids on the top Token Holder in the stack.  They're a bit tough to get on at first, but they're not too bad once you get the hang of it.  The lids are very thin so that they can bend to open up the tines and snap into place.

As always, the .blend file and pre-supported .3mf (including the one that I used to print this on my Prusa MK3, although the support points should work for SLA printers) for this model are available to my patrons at https://patreon.com/VirtuallyJason.

3/26/26 Update: I've added the Magnet Install Tool to this file.  It's a little platform to help get the magnets into the slots.  Remember that the polarity of the magnets on the high side need to be the reverse of the magnets on the low side, so what I do is install one magnet in the low side, then put a stack of magnets onto it.  I put this tool, smooth side down, on top of that stack and place on final magnet into the little tray.  Then I split the stack in half, flip the tool over and slot it onto the wall of the Card Holder's high side.  If the magnet slot is loose enough, you can just use the magnets on the back of the Install Tool to slide the magnet into the slot, otherwise you may need to use the Plunger to push it in.
