Yes! The 6X6 OSKAR and ACME share the same dimensions where that clip fits. It is an optional part, necessary if the sliders on your camera are excessively slide-y. A bit of gaffer tape works quite well, too - and won't get knocked loose in your bag. I have recently worked out a self-clipping slider set. If you haven't printed that part yet, I can modify the ACME sliders so that you won't need a clip. So many projects! Let me know if that would be of interest!
