A fully 3D-printable stitching pony designed specifically for leather craft and hand saddle stitching. This clamp combines quick-action work holding with customizable ergonomics.

Key Features

  • Single-Flip Cam Lock: A unified cam shaft clamps and releases both ends of the jaws evenly with one quick flip of the lever.

  • Adjustable Ergonomics: Features 0 to 45 degree tilt and full 360 degree swivel rotation, both locking securely in positive 15 degree click-stops.

  • Leather-Safe Pocket Design: Your work piece hangs freely in an open pocket between the jaws. Rigid internal ribbing prevents jaw flex, while flexible TPU grip pads hold leather firmly without marring the surface.

  • Modular Mounting: Bolt the pillar to either the included desk clamp (fits 10 to 45 mm surfaces) or the sand-filled weighted base for portable tabletop use.

  • Support-Free Printing: Every part is oriented and designed to fit a standard 250 x 250 mm build plate with zero supports required.

Bill of Materials

  • Filaments: PETG (structural body, jaws, and gears) + 95A TPU (jaw grip pads)

  • Bill of Materials (BOM)

    Metric Fasteners (M5)

    • 2× M5 × 65 mm hex-head bolt, full thread (ISO 4017 / DIN 933) — Ear tension bolts; head captive in the trunnion

    • 6× M5 hex nut — 2 captive in thumbwheels, 2 for front jaw, 2 for pillar/base

    • 2× M5 flat washer — Under the thumbwheels

    • 2× M5 × 30 mm hex bolt + 2× M5 nyloc nut — Hinge pins (one per end knuckle)

    • 2× M5 × 20 mm hex bolt — Front jaw to tilt bracket (get 4× if building the weighted base instead of the desk clamp)

    • 2× M5 × 16 mm hex bolt — Pillar to desk clamp (omit if building the weighted base)

    Metric Fasteners (M8)

    • 2× M8 × 50 mm hex-head bolt + 2× M8 hex nut — Tilt and swivel (head captive in bracket/yoke foot, nut captive in knob)

    • 1× M8 flat washer — Under the tilt knob

    • 1× M8 × 80 mm hex-head bolt + 1× M8 hex nut — Main clamp / pivot assembly

    Rods & Springs

    • 2× 6 mm carbon tube or aluminum rod, ~225 mm length — Jaw stiffeners through the full lip (optional for thin leather)
      *Rods can also be 3d printed however I would do them in halves length wise to improve structural integrity.

    • 2× Compression spring, ~8 mm OD × 25–30 mm L, light (~0.6 mm wire) — Around the tension bolts to push the jaws open
