Adapter for a retrofit head-up display in the car or camper van. Based on a fit for a Fiat Ducato Camper Van (Bürstner Lyseo), the .step file for individual mods is included.

The dimensions are in the following drawing (mm):

Easy to mount above the speedometer on the instrument panel (e.g. with double-sided adhesive tape). 

The head up display itself can then be mounted on this straight adapter with a self-adhesive Velcro fastener.

Print in PETG or ASA with at least two perimeters as this zone can get quiet hot inside during sunshine.
