Volvo 740 voltage/turbo gauge frame.

thingiverse

This frame allows you to add an original turbo or voltage gauge to your Volvo 740 dashboard. There are 4 locator pins in the frame. The same file fits both gauges. As you install the frame, you have to cut off the 2 extra pins. The rough surface finish in the pictures is achieved with a PEI bed. If you want a smooth surface finish, a glass bed is required. The recommended material is ASA due to the thin pins. However, PETG might also work.
