I bought a Meade 644 flip mirror, however, the short adapter - "SCT male to 3 thumbscrews" attachment was missing (indicated in photo). A friend has kindly 3D printed one but for longevity, I seek a spare metal one...

Does anyone have a spare, or can make a metal one for me, or know of a stockist, please?
