CF Card Holders for Gridfinity

EDIT - STOP - the diagonal version of this model is fine but the other version is a bit rubbish. It works but the front CF hole is too close to the front of the box. It's not my finest work. Don't download it. I'm leaving it here to remind me to tweak the design and re-upload it. If you really want - you can absolutely download it and use it - it works fine, but it just doesn't have finesse. Ok with that in mind, please don't downvote this model as I'm going to improve it shortly :) 

I see none of you weirdos use CF Cards. Well, old school photographers still use them because they are cool. Also they slip out of your hands less often when unloading media in the rain whilst walking backwards looking at something else.

Anyway, here are three different versions. They all hold the cards at a slight angle:

1. Diagonal - holds 4 cards, which will extend beyond the bounds of the 1x1 grid, just to mix things up a little
2. Vertical Grabbable - holds 5 CF cards sticking up out of the base.*
3. Vertical Stackable - holds 5 CF cards but the box extends above the top of the cards, so you could stack other Gridfinity items on top.

Fun fact: CF cards have little lips on one of the long edges. I didn't even notice that until after I printed. Anyway the revised version has space for lips on both sides, so the cards can be placed in either orientation.

Enjoy, fellow lovers of CF cards!

* I always prefer to include the Gridfinity stackable lip even on non-stackable designs, just in case you want to re-purpose the part somehow, or if you no longer need it, then you could at least use it to raise up other Gridfinity parts.
