Proxmark3 Easy Strong and Slim Case

Though by design in order to keep bulk and weight to a minimum, the original model was quite flimsy and susceptible to breakage (especially when interacting with the button).

Note: There are two versions of the “Slim” case that accommodate different revisions of the Proxmark3 Easy board. See the update below.

This version:

1. Beefs things up a fair bit
2. Significantly thickens the end portion of the case to make printing easier
3. Moves the cutouts to match the older version of the Proxmark3 Easy
4. Adds holes for LEDs
5. Makes the button easier to press
6. Makes surfaces flatter for better stability
7. Integrates the screw holes with the main body rather than having them stick out (at the expense of making things a bit bulkier)
8. Makes the LF antenna shape sunken rather than raised to make things a bit more stable when resting on the device
9. Adds a card-shaped indent for HF

There's a bonus slim version, which requires you to remove the middle circuit board (which serves no function) and the two screws and mounting posts nearest to the HF antenna end. BE CAREFUL WITH THIS ONE - it's a really tight fit, and could end up being a one-way transaction when it comes to inserting your Proxmark. You may have to cut it out if you wish to remove it, or you may have some luck pulling at one of the board spacers with some pliers. To use the slim version, you have to leave the rear screws and posts out completely.

Print with a 0.4mm nozzle. For the main body, print standing on its open end. For the lid, print on its face.

The lid can be affixed with 2xM3x8 bolts

Update 9th December 2024:

I had to buy a new Proxmark3 Easy, which has a slightly different PCB design to my last version. This meant the case no longer fit. I've added a new variant of the “slim” model that works with this new case. You'll know which one you need based on the USB port layout. If your button and side USB port are next to each other, you need the original version. If there is a large gap between the button and side USB port, you'll need the new version. The only downside of the new version is that you can no longer access the side USB port - it's too close to the front edge of the board to make a cutout for it without affecting the functionality and aesthetics of the case.

Others had been asking for this revision, so: Merry Christmas.
