Description

Before you spend hours printing a pod or panel: this set shows in about 40 minutes whether your printer and filament hit our dimensions.

  • Three rings for the 52 mm gauge body with +0.2 / +0.4 / +0.6 mm clearance (1, 2 or 3 notches). Our models use +0.4 mm. If another ring fits better, you know how to scale.
  • A 6 mm tall single-DIN sample with crush ribs: push it into the slot and feel whether it clamps.
  • An M3 test block: drive in a set screw and check that the thread holds.
  • Everything hangs on thin bars and is snapped off after printing.

Print in the same material as the final part (PETG, ASA or ABS): ASA shrinks more than PETG.

Shows whether +0.4 mm fits; otherwise scale the model accordingly.

Material and temperature

Shaded location: PETG is sufficient, ASA is the more robust choice. PLA is unsuitable in a car – it starts to soften at about 55–60 °C.

Print orientation: Flat on the bed, as the file is laid out.

FAQ

Which material should I use for this trim part / clip?

Recommended: PETG (alternatively ASA, ABS). Shaded location: PETG is sufficient, ASA is the more robust choice. PLA is unsuitable in a car – it starts to soften at about 55–60 °C.

Do 60 mm gauges fit?

Only if the body is 52 mm and just the bezel is larger. The bezel then rests on the front. This pod is not made for gauges with a 60 mm body. If unsure, print the included tolerance test ring.

Do I receive a printed part?

No. You get the print files and print the part yourself or use a print service. We email you the download link.
