Novoflex in Germany (https://www.novoflex.de) creates very nice camera accessories. However, they have a bit of their own interpretation of Arca Swiss style quick release plates. If I try to put their great QPL-Video plate in my RRS-Quickrelease clamp (or in fact every other clamp I own), they simply fall through. This spacer adds 0.7mm of height, thus make them compatible with my clamps. You may print this part and use as you wish, however, be advised that I neither guarantee that it fits for your clamps nor do I accept any responsibility for any purpose. This part is not an original part of Novoflex, nor am I affiliated with them in any way. Novoflex, Arca Swiss, QPL-Video are all brands and trademarks belonging to their respective owners.
