Oxygen xpan Film Rewinder Springback Version

I personally recommend using a rotary knob film advance; this lever-based system feels somewhat unreliable

Required accessories:
One rubber band (adjust to your preference); they will break with prolonged use

A tube of super glue, to bond the one-way bearing and the lever
