compact card holder - 3d printed model 3Dプリントモデル stl, から JSugahara

this card holder can store up to 6 cards (credit cards, debit cards, business cards, etc.) and also has additional space for id cards (up to 3 cards). it is a compact pocket-size design. not recommended for money because it has no clip to hold the bills inside. also as it is 3d-printed, it has no protection against magnetic fields.

final dimensions:
9.5 cm x 7.9 cm x 1.4 cm (around 3 3/4 in. x 3 1/16 in. x 9/16 in)

it is designed in 2 parts that can be assembly together (with a little use of force) in the hinge. no glue needed.

the hole in the base let you put your finger inside to pop out the cards. this improvement let you take your cards without the need to turn all the holder around. the same is for the hole in the id side. this allows you to slide the card with your finger avoiding the need to turn around the holder.

recomendation:
i got better results printing it with 3 layers of thickness and medium hollow fill. can be printed at 0.3 mm but you get a smoother result at higher resolution (as 0.2mm or better), but that increases the print time. i got better results using abs filament.

also i have printed (with better results) the base in horizontal layout but the id holder in vertical layout. this ensure that the orientation of the filament will be perpendicular to the force of the moving parts. this prevents that any of the parts of the hinge collapses.

(when i printed both in the same layout or the hinge opening collapses or the middle pin collapses, causing the hinge to break.)
