These are parts for the DIY flaps gauge on the site, both V3 & V4.
 
The decal plate is constructed from 3mm Acyrilic, painted black and then laser engraved. Fully back-lightable and looks stunning. 
 
The clear acrylic lens can also be purchased from the site. Constructed from 2mm acyrilic and comes with a protective film front and rear. 
 
Please Note: This does not include all parts to build the Guage. You will need the files and a 3d printer. Hopefully, in the future, we can offer the complete unit.
