Yu-Gi-Oh Duel Blade for 2 Players

This is like a Duel Disk from Yu-Gi-Oh, but it's designed to be a practical to use system compatible with the modern rule set. So instead of looking like the Duel Disk toys or the ones in the anime, it's a lot slimmer and lighter so it won't get in the way of most daily tasks. It has a more robust method than the toys for using the cards, which is compatible with XYZ monsters (up to 7 cards can be overlayed) and link monsters. It's a 2 player design so it can always be used with no need for the other person to have one of their own in order to play a game. The new sleeve design has built in life points counters for both players, as well.  This Duel Blade does not handle out of play cards. The deck, extra deck, graveyard, and banished cards are meant to all be dealt with by a separate device; I didn't ignore the out of play cards, I just don't think they're best handled by being in the same place as the Duel Blade because a deck of cards is very bulky and doesn't easily fit on the arm without a great hinderance to activities.

I included 2 alternate designs for the sleeve, because I had been using the old one myself until I recently upgraded it with the new sleeve design. I would suggest using the new sleeve because it's more feature rich than the old one, and better at the features the old one has, but it does make the Duel Blade more top heavy.

When you print the Play Zones, they must be printed with one of the two flat sides on the build plate. The bottom layers of the Play Zones will almost certainly fuse together, but they can be easily broken through using a credit/debit card.

To put the Duel Blade together after printing all parts, you'll need some super glue, and a cheap strap that can fit through the holes in the bottom of the sleeves (anything smaller than 2mm * 26mm will work), which can usually be found at Walmart. And you may need some transparent scotch tape, depending on how the life points counters behave.

You'll need to print: 

5 Play Zones

1 of each segment

1 new sleeve and 1 Strap Loopy

or 1 old sleeve and 2 Strap Loopies

10 Life Points Counters if using new sleeve

Assembly instructions:

1. Glue the little legs at the bottom of the play zones to the holes at the top of each segment.
2. 4 of the 5 segments are horseshoe shaped, slide them into each other such that the horseshoe shapes are pointing the same way and the legs of the horseshoe are going underneath the play zones. There are flexible tabs on the bottom of 4 of the 5 segments as well, these should also be pointing the same way. You should feel or hear a click when the tabs are in the corresponding holes of the previously numbered segment. The first click when assembling should happen in the opened state of the Duel Blade, pushing the segment farther until you hear the second click will move it into its closed state. You may have to push down the tabs manually when inserting the segments into each other. This should be done in the same order they are numbered (so 1 into 2, then into 3, then into 4, then into 5).
3.  A) For the new sleeve, insert the strap through the hole at the bottom of the sleeve, leaving a long length of strap on both ends of the hole. B) for the old sleeve, 2 straps are needed, insert one end of one strap through one of the small holes, then loop the strap over the nearest big hole such that it can rest atop the flat surface and through the small hole mirroring the first hole you sent the strap through
4. String the strap(s) through the strap loopy/loopies in whatever way is convenient so that the sleeve can be secured on your arm.
5. A) For the new sleeve, insert the 5 segments (all should be one unit now) making sure that the tabs on segment 5 are in the same spot as the indentations on the top of the sleeve so that the tabs will be able to move out of the way when opening the blade. The 4 tabs on the inner walls of the top of the sleeve correspond to the 4 holes on the outer wall of the bottom of segment 5. This will be difficult and take a lot of force, and will not be easy to do, so make sure you get it right. B) For the old sleeve, insert the 5 segments (all one unit now) into the sleeve making sure that the tabs on the bottom of segment 5 are over the larger T shaped hole on the top of the sleeve. The 4 tabs on the inner walls of the top of the sleeve correspond to the 4 holes on the outer wall of the bottom of segment 5.
6. For the new sleeve, slide the Life points counters into the slots on the 2 sides of the unit. Test them to see if they fit well enough by sliding them to display the number 9, and if it falls out easily, apply transparent tape to both sides of the life points counters to make them slightly thicker so they'll stay in.

The Duel Blade should be done now. You can open the blade by sliding out segment 4 until you hear the tabs click, then segment 3, then 2, then 1, in that order. You can close the blade by sliding the segments back in in reverse order. The tabs on the segments are designed in such a way that if 4 is closed, then 3 is locked, and if 3 is closed, then 2 is loscked, and so on. There are slots to put your hand cards when you need to fiddle with your deck, on the new sleeve, they're shaped like triangles underneath the blade above the life points counters, you should put the cards in coming from the side rather than going straight forward because it can get pretty tight in there. On the old sleeve they take up pretty much the whole sleeve and they're positioned in such a way that they interfere with the play zones in segments 4 and 5, so they're very inconvenient to use.

I made a playlist on YouTube of myself designing the new sleeve model:
