This mount can be attached to the dash using 4mm or 5mm hex bolts, washers and nuts, just unclip the dash surrounding the speedo.

Once you have printed the mount, glue a magnetic mount (similar to the one in the link bellow) to the print. I used a silicone/mastic adhesive, but superglue should work.

Be sure to turn off the air vent behind the mount to prevent the print from melting (if using PLA) also position the vent lever touching the backside of the mount to stop any vibration while traveling. (see picture)

Supports are required for the back brace.
