Rollbar Collar for the new B7, the prices Team Associated charge for these little bits of blue is quite staggering so if you lose one or just dont wanna buy, then download these.

Theres a big and small for bigger and smaller rear rollbars, the inner diameter is 1.3mm for small and 1.5mm for big but in my testing, the 1.5mm was pretty snug on my 1.3mm rollbar so you may need to slightly drill. Ideally you want the bar to be fairly snug.

Can probably use PLA if not in a hot environment, but if so use PETG or ABS. A firm TPU may work? didnt try.
