You can buy this $365.00 worth Instant Back for Hasselblad (called "Hasselback"), but the focus doesn't work well. The Hasselback is approx. 3.5mm further back from origin film-plane. Therefore, a (major) misalignment is the result. Especially the worse when you take a photograph of a closer object with faster aperture. 

I designed an offset frame which is put under the focussing ground glass, which leads to the consequence that the original black square viewfinder doesn't fit when using the adapter frame. So a second part needed to be designed, which can be slided on the ground glass now, staying in place by the Escura Hasselback when mounted. This design is made for Hasselblad model 501CM. Other models may vary, why don't you just check it out?

With these improvements the results of close-up objects miles better than without. I am happy with the result and happy I could sove this problem. 

Designed with TinkerCad, printed with my MK4 in eSun PLA black matte. Please use ca. 3mm brim for the viewfinder. That will prevent your print from warping.

Have fun and happy printing.
