A rigid, fully 3D printed card wallet with no springs, elastic, screws or metal. One solid sleeve holds 1 to 8 cards (or 1 to 6 in the slim version). Optional versions add a coin drawer and a banknote drawer. Everything prints without supports. Printed and tested on a Prusa CORE One: the 8-card sleeve and the version with coin and banknote drawers both work as designed.
How it works
Click latch instead of a spring. The last 25 mm of one side wall is a leaf spring with a nose that sits in front of the rounded corner of the cards. At rest the latch is unloaded: nothing is under permanent tension, so it does not creep or go slack over time, not even in PLA or in a hot car. It only flexes 1.4 mm for a moment when the stack passes.
Any number of cards. The nose spans the full thickness of the cavity, so a single card is held as firmly as eight. No filler plates needed.
Cards out: thumb in the V notch at the closed end, push the stack about 9 mm through the click, take the cards at the mouth. Cards in: push them back with a fingertip (basic version) or press the stack flat into the recess at the mouth (drawer versions).
Coin drawer (
_muntenversions): a loose tray with six round pockets, one coin per pocket, three for all euro coins including 2 EUR and three for coins up to 50 cent. The pockets face the back plate with 0.3 mm of air, so coins cannot stack or escape. The drawer has its own click latch and a pull tab in a V notch of the back plate.Banknote drawer (
_munten_biljettenversions): a flat tray for up to six banknotes folded in four. It opens at the closed end of the wallet, so each drawer has its own pull tab and they never get in each other's way. Holds any euro note, including 200 EUR. Zero to six notes are held equally well because nothing is clamped.Money clip (
_geldklemversions): a simple clip plate on the front for one folded note. The banknote drawer is the better solution; the clip is kept for those who want the thinnest option with a note.Ribbed roof: the wall that becomes the roof of the cavities in the print orientation is made of short transverse ribs with 45 degree grooves, so the slicer only has to bridge 4 to 7 mm at a time. No support, no special bridging settings.

"hoes" = sleeve, "pasjes" = cards, "munten" = coins, "biljetten" = banknotes, "geldklem" = money clip, "la" = drawer. Cards are standard ISO 7810 ID-1 (85.6 x 54 mm, credit card size). Designed for euro coins and notes; other currencies may need different pocket sizes (see the source script).
Printing
Sleeve: print in the orientation of the STL, standing on the narrow side wall with the slots. Add a 3 mm brim. No supports. In this orientation the latches lie flat on the bed and flex along the layers, where the print is strongest.
Drawers: flat, floor on the bed, pull tab up. No brim, no supports.
0.20 mm layers, 4 perimeters, 0.45 mm line width, 15 % infill. Tested on a Prusa CORE One with a 0.4 mm nozzle.
PLA or PETG. There is no permanently loaded spring, so PLA is fine. PLA gives a firmer click; PETG a softer one. Calculated holding force of the card latch is about 3 N (PETG) to 5 N (PLA) for the 8-card sleeve; the drawers hold about 4 to 7 N.
After printing: flick each latch tip (at the mouth, and at the closed end for the banknote version) outward once with a fingernail so it is free. If a latch is stuck because of a squashed first layer, run a knife through the 0.6 mm slots.
Print time for the 8-card sleeve with both drawers is about 2 hours; the basic 8-card sleeve about 50 minutes.
Tips
Open and close the coin drawer with the back of the wallet facing up; the other way round the coins fall out as soon as a pocket clears the sleeve.
Fold banknotes in half twice. Push the stack up through the hole in the floor of the drawer to take it out.
Do not hold the wallet on the latch tips while pushing the cards out; they need to flex sideways.
The banknote version needs the new coin drawer with the small notch at the back (included). An older coin drawer without the notch fits all other sleeves.

The whole design is a parametric FreeCAD script (pasjeshouder_v7.py, included, run with freecadcmd pasjeshouder_v7.py). It regenerates all STLs, computes the latch forces and checks that cards, drawers, coins and notes never collide. Useful parameters if you need to tune the fit: GRENDEL_L (card latch length, longer = softer click), GRENDEL_L_MUNT and GRENDEL_L_BILJET (drawer latches), SPEL_T (card stack clearance), LA_SPEL_X (drawer end play), VAK_GROOT / VAK_KLEIN (coin pocket diameters), BILJET_DIEP (banknote depth).
