Well deatails are:
Latest and best verion of card cover comprises of 3 parts:
-2x cover with logo (support used)
Both are printed with different technique. Covers and logos are printed with 0.25mm nozzle and 0.1mm layerheight, Printed in one piece face (logo) down (just switched colors in between). Multi colored parts of logos are printed separateley and then glued into cover (i have nice Virtus pro cover, coming soon).
Body, or mid, is printed with 0.4 nozzle, 0.5 extrusion width (because walls are 1mm/2mm thick), also support is used. There is nothing to secure cards except friction, but it's well designed because it is both horuzontal and vertical fricion which are preventig card from drop out. Material is PLA. I use this cover on daily basis
