These are custom bard game / card game card trays. They stack for easy storage inside your board game box. These are sized to fit Dominion cards.
Trays allow interlocking in multiple orientations to support other layouts.
The interlock features are spaced at .2mm. Therefore you may need to adjust your 3d printers settings if you are having a hard time interlocking them. I print with a 0.25mm nozzle at 0.2mm layer heights.
If you need other sizes, just request them in the comments section and I will get them posted up for you. I can also adjust depths.
These have a 4mm stacking bottom to allow them to fit on top of each other without sliding off.
1/23/18: V2 is out. Please print V2 if you are just now printing!
V1 is still provided for those who printed prior to V2 release. V2 will be the interlock I use for all future designs.
A couple of design changes were implemented that make V2 no longer compatible with V1. Namely the spacing of the interlocking triangles. This should allow future changes in card sizes to be compatible with each other. With the new changes I can very very easily adjust the sizes for cards and the model will update automatically. Let me know in the comments if you need different sizes and I can make them very easily.
