I'm not a 3D designer or a maker, just an occasional consumer... And I'm wondering if anyone has a design for a gantry that holds a mobile phone or tablet over a slot car track?

   

Scalextric are releasing a new timing app in July / August and have some cardboard 'hardware' bundled in a new Rally set scheduled for August...

       

I took these images at the UK Slot Car Festival a couple of weeks ago. The Scalextric team member who demonstrated the app to me agreed that a 3D printed gantry would be much better - although they've also used Lego to build a pretty sturdy gantry.

Essentially, the app is set up so a line on the screen lines-up with the centreline on the track below - really simple. Obviously, there's the issue of different phones and tablets being different sizes - hence the Scalextric gantry having a simple, flat top. Also, different track systems are different widths - and some may use it on a routed track.

Is there anything out there already - or is this something that's of interest, given that this app is likely to be taken up by a lot of home racers and at slot rally events?
