This is a simple Button Box that can be mounted on a aluminium profile

Its uses a zero delay arcade USB board for simplicity and has two M8 holes in back box used for attaching the Button Box to your rig and a side opening for the zero delay arcade USB cable. 

The front part has been printed on a carbon fibre texture plate and has two colours, so if you don't have the AMS then just replace red with your main colour, the back box pritned on a standard textured PEI plate. 

I've provided three different back boxes depths on separate plates … 58mm, 48mm and 38mm deep. Choose the one that works for you, don't need to print them all. The one one the photo is 58mm deep, for reference.  

The holes for the he small buttons are 8.2mm 

Igition button hole is 16.2mm

Engine Start button hole is 19.2mm

Larger silver button hole is 16.2mm (I mapped this button to ESC on my keyboard and I wanted to have the ability to pause or go to the pits quicker without  having to reach for the keyboard)

the 8mm buttons are used are those: [https://www.aliexpress.com/item/1005005628118782.html?spm=a2g0o.order_list.order_list_main.91.12321802rIJuJP](https://www.aliexpress.com/item/1005005628118782.html?spm=a2g0o.order_list.order_list_main.91.12321802rIJuJP) They are back lit  so I have just wired one side of them to +5v and the other to ground

The ignition button is also a backlit one, I used one of those [https://www.aliexpress.com/item/32877295591.html?spm=a2g0o.order_list.order_list_main.393.7ac01802l0wgxV](https://www.aliexpress.com/item/32877295591.html?spm=a2g0o.order_list.order_list_main.393.7ac01802l0wgxV)

Zero Delay Arcade USB board used is this one [https://www.amazon.co.uk/dp/B09SKY8GMZ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1](https://www.amazon.co.uk/dp/B09SKY8GMZ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1) 

Engine Start button was this one [https://www.amazon.co.uk/dp/B07G8YT6DN?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_12&th=1](https://www.amazon.co.uk/dp/B07G8YT6DN?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_12&th=1), but it's pretty expensive 

… I've share the button holes above, so any buttons that fit those diammeters would do.
