pen engraving jig 3d model

A custom horizontal pen and pencil engraving jig compatible with an xTool F2 laser engraver. The jig holds 10 pens and pencils laid flat in parallel channels for consistent laser engraving, directly inspired by typical pencil jigs like those used for hex pencils. Base: A square plate, 107mm × 107mm × 5mm, with slightly rounded outer corners (≈ 1 mm). Grooves: The top surface contains 10 parallel channels running left‑to‑right for pens/pencils to lie flat. Each channel is sized to cradle round pens: V‑groove with 90° included angle, top opening ≈ 12 mm, depth ≈ 4 mm. A flat alignment edge or micro groove (≈ 1 mm wide) runs along one side inside each channel to prevent the pens from rotating, ensuring consistent engraved orientation. Channels are arranged in 2 rows of 5, with spacing: Center‑to‑center X spacing: 22.75 mm Row Y spacing: 25 mm Outer margins are balanced so the channels are centered on the base. Optional end stops (≈ 2 mm high) at each groove end to keep pens from slidin
