Maker Wallet Redesigned (Magnets, 6 cards, knurling)

This is a modification of the Maker Wallet by Agustin Arroyo, with some fixes that make it work much better in my opinion. 

This remix adds holes designed for small magnets. 4mm in diameter and ~1.8mm thickness. These magnets help lock the lid in place, and allow me to more easily use the parts without glue, which makes it quite easy to swap any pieces quickly. I also wanted to hold more cards in my mod, so I used Joe Schmoe's 6 card remix as a strong starting point. 
 

⚠Be careful with magnets and magstripe cards⚠ 

The magnetic strip on a credit card can be erased with a strong magnet. I placed all the magnets on the bottom of the wallet in order to (hopefully) prevent any issues here. Where I live, magstripes are rarely used, and so I am not personally very concerned. However, I recommend you be careful, and use your own judgement, to prevent issues there.

List of changes from Agustin's original design: 

• Holds 6 cards instead of 5 (thanks to Joe)
• Larger rotation in the cover, slightly larger base, removal of unneeded nub (Joe)
• Uses 4mm magnets to lock pieces in place
• Guide has been added to lid to better lock into cash compartment track
• Ramp has been added to cash compartment to help prevent lid from getting stuck when closing
• Fine Knurling has been added to the base and lid to help improve the wallets grip when in pocket
• Grip lines added to lid to help with one handed operation
• Larger locking bump holds closed more tightly
• Steeper overhand on locking track helps to hold lid more firmly
• Cash compartment has been reduced in size slightly
• Cash compartment now has a wall where there was previously a gap
• Base now has a small recessed track for the lever to slide in
• Empty portion in lid guide track has been filled in
• Some slight geometry changes on the corners, to help the lid fit more evenly

Things that could still use improvement: I'd like to experiment with slightly shrinking the base size, as mine is very roomy for my cards. I may redo the cash compartment a little, too, so that it more easily fits cash without having to align it just right. I also find that currently, the locking bump is a little too strong, (easy temporary fix is to slightly cut some of it off). I also would like to try changing the part of the lid which holds the cards in place, to extend down below the base, and lock in place, because mine sometimes allows one card to break free. In it's current state, however, I do find the wallet quite usable. 

 

Assembly:

• Print a base, lever, cash compartment, and then lid. 
• Add magnets to the holes, being extremely careful to place them in the correct way, so that the ones in the lid actually attract the ones in the cash compartment and base. You might want to use a marker to help you with that.
• Press the magnets down firmly using a small blunt tool. I used some pliers I happened to have on hand, to press in the magnets after they were partially inserted. They should fit very tightly with friction, however, depending on your printer's tolerances, you may need to add glue, or widen the hole slightly using a tool. 
• Add the lever to the base, slide the cash compartment into it's slot, and then add the lid on top of that. Use the photos in the original as a guide if you can't see how they fit together.
