Just got two brass FM bipins for my two Mag85 hosts. One is an older red 3D, one a new pewter 3D. The adaptors both fit in the newer host, but don't in the older one, even though visually they look very similar. Did Mag change the size of the PR base holder at some point? I've PM'd FM and I'm sure I'll hear from him but I was wondering if anyone else had this problem?
