This mod can be mounted in the center of the steering wheel. You can coat the outer ring with adhesive vinyl (as in the picture, carbon-like vinyl) and placing a round badge in the middle (inner badge diameter 35mm).
Thanks to Velcro stickers, you can also turn your smartphone into a dashboard directly on the steering wheel (we suggest to fix the dashboard to the base servo, because on the steering wheel it alters the weight and the centre of gravity).
Where to find the Velcro sticker You need a Velcro sticker measuring 10 cm x 4 cm. Here is where to buy: LINK This dimension is not mandatory.
Where to find round stickers The best are those with a dome effect (transparent resin). They are cheap and can be ordered in different online sites (also customizable, with your own design). Click here for an example site.
The smartphone app we recommend We love the "SIM Dashboard" app. Highly recommended: LINK
How to install it
Unscrew the 3 central screws of the steering wheel (3 shortest ones);
Glue the hardest part of the Velcro into the rectangular surface, as in the photo;
Attach the holder to the steering wheel, replacing the 3 original short screws with 3 longer ones (M4 x 15 countersunk head);
Glue the remaining part of the Velcro (soft part) to the back of your smartphone. It is advisable to buy a silicone cover, which should always be left on the steering wheel.
Printing Requires support only at the bottom of the badge slot. To make the pieces fit together well, you need to calibrate the printer. We recommend an Infill higher than 50-60%.
