DSLR Film scanning jig

I built this model for scanning my 6x6 negatives easily with my DSLR . This is currently setup for 6x6 but can be adapter to support 35mm with masks or 6x4 in future. 

My objectives were to make it easier to guide the film without scratching it. 

Print: Easy to print with no support. The only issue could be warping due to the length of the model.
