A simple card holder, designed to hold the collectible cards found in the Titans Return Transformers.
(The cards are about 65mm wide.)

It should scale well, if you need something wider.

The geared version took about 20 minutes to print for me. If that's too long or if you don't want the gears, I've also uploaded an ungeared version, feel free to redecorate it :-D

Doesn't Matter

0.3

whatever

Printed with a 0.6 nozzle at 0.3 layer height - about 20 minutes for the geared version.

And a very small bit of Meshmixer, to trim the gear (remove unneeded axle and make sure it's even).

It's a rather simple design, obviously. Basically a roof with a 1mm slit.

I've capped the tip, so it's a bit flat, though you don't really see that anymore. Also, just to make it nice, I've made a slight round indention, so the card middle is a bit more visible.

I've had to adjust the gears quite a bit - added a big axle to have some rounding where it connects with the base holder, and make it wide enough to be printable - depending on your printer, a smaller gear might be printable, but with 0.6 nozzle and 0.3 layer height, this is the least it had to be :-)

Apart from more/better decoration, I think the main problem with the holder is that it obscures too much of the card - unfortunately the cards themselves only have about 1MM space that isn't used for the design, so I'm not sure if there is a good way to get more visibility, apart perhaps from making a deeper indentation in the middle?

Also, if someone found a way to make it more steampunk-ish, that'd be great. All I know is how to slap on a few gears and maybe try to fake a piping, but in this case everything's so small...
