Straight extension for GoPro Fusion helmet mount?

Recently got a GoPro fusion and am looking for helmet mount options and it sounds like 10" is the optimal distance for wingsuiting as far as stitching and visibility. Anyone know of any 10" extensions on the market? Most of the other folks I've talked to have made their own but I thought I'd check first.

Anyone have a DIY version that works well that they're willing to share with the group?

if you google " aluminum gopro extension arm" there are tons for under 20 bucks. Prolly buy a straight one as opposed to a curved one so the gopro software can erase it easier.

Perfect, just needed the right search term. Thanks!
