Travel Cribbage Peg Track — Captive Slide-In Pegs, 1 to 6 Players

A travel cribbage score track that fits in a pocket — with scoring pegs that can never fall out . Each player gets one peg riding a hidden T-channel : the peg's foot is wider than the top slot, so once it is on the track it only slides 0 → 10 , it can't be lifted off or lost. A kinematic ball-detent clicks the peg into every score station — a rounded ridge under the foot nests into a little 45° Vee groove at each number — so the peg advances with a firm push and self-centres exactly on each number , no slop.

Bundled in every player count, 1 to 6 — one lane and one peg per player. Pick the file for your table.

Print-in-place did not survive the real printer (the captive peg fused to the channel), so this is the reliable redesign: everything prints as separate, clean parts , then you assemble in seconds —

• Print the body, the peg(s), and the end cap.
• Slide each peg into the open end of its lane, onto the track.
• Snap the end cap over the open end — the pegs are now captive.

Nothing to lose, and every part prints flat, deck-up, supportless .

• ..._2color.stl — the housing. Two named solids: the body and the flush number inlays . In Bambu Studio: Import → right-click → Split to Parts . For a two-colour track assign a second filament to the numbers solid; for a single-colour track just delete the numbers solid and the digits stay as clean engravings .
• ..._peg1.stl , ..._peg2.stl , … — the sliding score pegs, one STL per player so you can print each peg in its own colour. All pegs are the same shape; the count matches the player count.
• ..._cap.stl — the slide-in end wall that encloses the pegs.

• PLA or PETG, 0.2 mm layers, 3+ walls
• All parts flat on the bed, no supports, no brim
• Print the pegs in a contrasting colour so each player's is easy to read

Parametric — the whole thing is one OpenSCAD file (attached). Tune the score range, station pitch, lane spacing, peg size, and every detent / slide clearance, and re-export any player count you like.
