A pair of adaptors to mount your Bose A20s onto some 3M earcup mounts.
There is a person selling his own design, and if you want to pay $75 for his go ahead.... here is his website. https://www.skycowboysupplyco.com/product-page/scsc-pilot-helmet-stirrup-convertor

These are not copied from his design, I started designing these before I even knew about his. I originally had a hard time designing this and almost gave up, I did some googling and found a person who makes adaptors for the A20s, I reached out to see if he would sell me just the files but he declined. That drove me to continue designing my own until I got them right! Once I got them right I posted them here for everyone to have access to for free! Well.... This person reached back out to me demanding I take down my files claiming copyright infringement and now he has flagged my original upload on thingiverse. So I am reposting them now instead of waiting on thingiverse.

I have emailed thingiverse to try to clear this mess up. I sent them the entire conversation between myself and the person who sells his own version of A20 adaptors.

I will be posting these files on all the other 3d printing sites as well as some of the facebook groups!
