An access-card holder made for two cards.

Informacje o modelu

I wanted a card holder that worked more like the way I wanted.

The ones I either got were either tied to a neck-band, had holes at unsuitable places, could only store one access card at a time or were too bulky.

So I added (another) card holder to the internet.

PETG or PLA
Time with 0.2mm and 0.4mm nozzle (MK4S): 81min.
Infill: 15% - does not matter, since infill is only used for some layers at the very bottom.
Prints standing upright.
Uses ~ 35gr filament.
Remember to mark some areas to block supports. Only the card holders on the top deck on the side and the band slot at the bottom require supports (v2.01) - see Slicer image. The rest should print fine without it.
Consider rotating the model to reduce swinging during prints.

The version number and ID is for my internal use. Feel free to remove it if it annoys you.

When putting two cards into the holder, sometimes the card on the inside couldn't be recognized but card-readers. This version closes the thump-opening in the middle and puts it's on the back. So both cards are separated by a complete wall, but are open to their either side. This seems to work better with card-readers.
Changed the distance for holders of the upper card a bit, making the card a bit more loose.
Tampered the lower parts of the front card-holders, so they can be printed without supports (as long as you can print 45 dg angles)

Since v1.22 broke at the handle, the baseplate (and the handle) got thickened with a millimeter.
The holes in the handle were moved a millimeter lower to increase the strength on the stressed part.

Removed the stopper on the lower layer and added two struts inside. This will increase the resistance of the lower card when sliding in and out and keep it in place. The previous stopper was stopping too well and made removing the card hard.
