Wine Red Lens Film Repro Tube
Print Profile(1)

Description
A simple wine red lens repro tube for film duplication, with a focusing distance of approximately 10 cm
It is recommended to use with the macro head shown below (a more comprehensive film duplication system will be released after I complete it)

A 90mm lens core was chosen, with an outer diameter of 43mm. The lens barrel is designed with 4 M3 heat-set insert holes. If the lens core is not tight, you can choose to insert heat-set nuts and secure it with screws. Adhesive can be used between the lens barrel and the bayonet ring (I used AB epoxy)
Finally, if you print with non-black matte material, remember to line the inner wall with flocking fabric for light baffling!
