Lasercut Nintendo Switch 16x game card holder with magnetic latches

thingiverse

I wanted a game card holder for all my Nintendo Switch games and had to over-engineer my own. Features: * space for 16 game cards: four slots each on top and bottom; double-sided (backside not shown) * see which game is which at a glance, thanks to clear acrylic top cover * strong magnetic latches * NO ADHESIVES USED! The design is pretty flexible: It shouldn't be too much effort to modify it so as to have one side or only one lid per side – originally, it was designed for only three game cards per row. I wouldn't recommend it, but it's possible to add more cards per row… Materials: * laser cutter * 4mm HDF (~15x38cm) * 4mm clear acrylic glass (~6x30cm) * 20mm screw posts (6x) * 12x4x2mm Neodymium magnets (16x) Lasercut everything in the SVG. Make sure to first cut out the holes (red lines), then the shapes (black). The blue shapes (with pink holes to be cut first) are the acrylic glass parts. (The light blue slices are just placeholders for the magnets, in case you don't want them or want to use less than I did.) I used 4mm HDF (game cards are ~3.4mm thick according to my measurements, which leaves a bit of wiggle room for the cards – perfect!), as well as 4mm clear acrylic glass for the top and bottom to see the content even when closed. Then, after semi-assembling everything, I inserted the magnets (partly stacks of two and three) into their slots. The length of the magnets ensures that the middle "spacer" parts stay fixed in place. (Originally, I had different magnets that weren't nearly as strong; that's why I added *stacks* of magnets to the design. Now it's almost *too* strong – on the other hand, it ensures that it doesn't open when carrying in a bag or something.) Finally, the screw posts are screwed together (with a bit of threadlocker to fix them together while allowing the covers to rotate). Works perfectly! Picture information: * finished product (3x) * visual assembly guide * (very) first design sketch * clamped-together, one-sided, single-row only, beta version Room for improvement: * a couple of mm's in thickness could be shaved off from the finished product by choosing thinner top, middle, and bottom layers (both HDF and clear acrylic glass; the layer with the game cards needs to remain 4mm); note that the screw posts would have to be changed and not all lengths might be available * magnets … I don't like the asymmetry, but it has its reasons; the batch of magnets I used in the final version are very strong, probably could remove a couple * the inner layers of the lids are fixed in place by the magnets on the narrow end – works kind of OK, but it could be better; maybe shave off a mm at the edge?
