Number Plate Keychain with 4 mm Keyring Hole

A flat 65 × 17 mm number plate keychain built around the three things that ruin a printed tag: a hole that tears out, lettering that runs off the right edge of the plate, and a border crowded with extra frames. The hole sits inside a raised black ring instead of hanging on a thin web of plastic, so a heavy bunch of keys has something solid to pull against. The registration line sits on one horizontal line, raised 0.6 mm so it stays readable instead of rubbing smooth in a week, and it starts clear of the ring so nothing touches the hole.

Print and fit

• Plate: 65 × 17 × 2.5 mm, corners rounded, smooth flat back.
• Keyring hole: one 4 mm through-hole at the far left, 7 mm in from the end so its ring clears the border, fully open through the base, with its own clear area so it never meets the text.
• Hole ring: a 9 mm black raised ring around the hole, kept neat and with no other decoration around it.
• Lettering: "PB 27 F 9146" on one line, raised 0.6 mm in a heavy bold face with even spacing, sized to fit the space between the ring and the right border.
• Border: a single thin black raised border around the whole plate, 0.6 mm high — no inner frame.
• Base: light grey, flat and unbroken underneath, prints without supports; the detail all sits on the raised top face, so a two-colour print or a paint fill both work.

The text sits a little right of the plate's true centre because the hole takes up the left end — a truly centred line would run into the ring. If you change the registration, shorten the text rather than the plate, or the line will overrun the border on the right side.
