Description

The shoe is an inclined tray that holds up to six decks of poker-size cards (63.5 × 88.9 mm) standing on their long edge. The tray floor drops 25° toward the dealer, and a weighted pusher on a T-rail slides down it and keeps the stack pressed against a front wall. The dealer lifts the front card up and out over the wall, which has a thumb notch.

The pusher is hollow. Twelve 30 mm steel washers go in a vertical pocket and a press-fit plug closes it, so the mass (about 180 g) does the pushing and nothing else is needed. The T-rail keeps the pusher square to the walls so it does not jam against the cards.

The body prints as one piece with a solid wedge under the tilted tray, so it sits flat on the table and prints without supports.

Why it sells

Card shoes are already shared for printing. MakerWorld 1287030 is a modular weighted pusher design, and its listing says it needs hot glue for final assembly. MakerWorld 1291639 uses rubber tension and is listed as holding six decks, though one commenter reports four with poker cards. A smaller ramp shoe at MakerWorld 1272868 holds about 110 cards, and Cults3D 2432229 is a paid dual-deck shoe with a discard tray. Board-game accessories as a category are covered in 3dprinterly's roundup. I found these on 2026-11-12 by WebSearch and did not find sales numbers for them.

The gap: the listings I found rely on glue or rubber for the pusher. This design uses a printed T-rail and a washer-filled weight, so it assembles by hand with a hardware-store item.

Who buys it

Home blackjack and baccarat players, poker-night hosts and teachers running probability games. They shop on Etsy and MakerWorld, and also buy printed trays from board-game accessory sellers. It is a gift for someone who already owns cards and chips.

Design overview

• One thing sets it apart: a washer-weighted pusher on a printed T-rail slides down a 25° floor, so no rubber band, spring or glue is needed.
• Channel 65 mm wide for 63.5 mm cards, 0.75 mm per side, so cards do not bind.
• Capacity of six decks at 0.35 mm per card (312 cards, about 109 mm of stack).
• Front wall 40 mm high with a 30 mm thumb notch so the dealer can lift the front card up and out.
• The tilt is built in. A solid wedge under the tray lets the body print flat and stand flat.
• The pusher plug is a press-fit disc that locks the washers in.

Dimensions

Parts list

Hardware and non-printed parts

• Steel fender washer, 30 mm OD × 8 mm ID × 3 mm thick × 12 (about 180 g). These stack in the Ø30.5 × 42 mm pocket.

Cards (not included): poker size, 63.5 × 88.9 mm.

Fits and tolerances

Modeling guide

Origin: front-left-bottom corner of the tray floor in the tray frame, +U along the floor toward the rear, +Y across, +W perpendicular to the floor. The finished body is the tray rotated 25° about Y, with the wedge filling down to Z = 0.

1. Tray: extrude a 160 × 75 floor 4 thick, side walls 5 thick × 52 high and a front wall 6 × 40.
2. Tray: cut the 30 × 12 thumb notch in the front wall.
3. Tray: add the T-rail, stem 8 × 3 plus head 16 × 3, on the floor centre from U 6 to U 160.
4. Body: rotate the tray 25° about Y, add the wedge down to Z = 0 and fillet corners 1.5.
5. Pusher: extrude 36 × 64 × 62, cut the T-slot 0.25 mm per side bigger than the rail.
6. Pusher: cut the Ø30.5 × 42 pocket and the 10° card face.
7. Plug: Ø30.3 × 6 disc.
8. Check: with the pusher slid fully forward its face touches the front card position (U 6) and at full rearward travel it still engages the T-rail head.

Print settings

Assembly

1. Stack the 12 washers in the pusher pocket and press in the weight plug.
2. Slide the pusher onto the T-rail from the open rear end.
3. Load cards with the pusher pushed back; set the stack against the front wall.
4. Release the pusher, then lift the front card up and over the wall.

Variants and upsells

Four-deck and eight-deck lengths (change tray_length), a matching discard tray, and a cut-card sized for the channel. Bundle with the Ball-Pivot Roulette Wheel as a casino-night set.

Risks and IP notes

• Cards stick on the rail or on each other. Mitigation: wax the rail; 0.75 mm per side card clearance.
• Pusher may not slide if too light. Mitigation: 12 washers, 25° tilt; the weight is the adjustable variable.
• Gambling-adjacent. Mitigation: list as a card-game accessory, no brand names.
• Crowded category. Mitigation: no glue or rubber.
• Cards of different thickness change capacity. Mitigation: state 0.35 mm per card in the listing.
