I've spent a while designing a fully adjustable compact neck support for my V20, after Larry assured me I needed one. It can be fully 3d printed unless you need a long support then I would say use 12x 6 mm aluminium drilled bar ( I've included a drill jig for the 5'5mm holes) All the instructions etc are on the maker world page. I have padded mine with firm foam and covered in leather. Feedback encouraged, and more than happy to test is with a race cage if anyone would like to donate one to me. all files https://makerworld.com/en/models/1398900-cruzbike-neck-rest-assembly#profileId-1450385
