Hipster PDA Index Card Wallet

I carried The DUMB Wallet for about a year, and decided that I also needed a similar concept to hold index cards for a Hipster PDA (shoutout to Merlin Mann!). The thought process began by pondering if I could just glue my DUMB wallet to my new index card sleeve, and then grew from there.

This wallet is designed to hold about 20 index cards and 5 credit cards, but the model is parametric. You can change those values fairly easily. The pen loop and tip guard grab the clip of a Zebra Sarasa Clip Gel Pen, but I have fine results with other clip pens as well.

This should print as a solid object regardless of infill settings since the walls are thin. I have included a wedge support structure for printers that need it, though I've found no need for the support on my Core One. I'm sure a bed slinger would have a heck of a time keeping the object from falling over. There is also a vertical version, which would require support material to be added. I recommend the 45° angled print.

For the customizer, this scad file requires the BOSL2 library. I have not tested non-standard card sizes, so YMMV on wall thickness and other details if those values are changed. In fact, there is a bug in my thinking that means changing the number of index cards is more involved. I may get around to changing that someday, but I think the 4mm pocket is pretty much perfect as-is.

Inspiration taken from wallet design – added index card and pen holder.
