4x5 film reel for Paterson tank

This is a reel to hold two 4x5 sheets into a two reel Paterson Tank.
I created it to be used with a rotary processor, but it can of course be used with a traditional inversion method, even if it's not very efficient, requiring 700ml of developer for just two sheets.
I printed in PLA and sprayed with an epoxy primer, probably printing it in PETG would be better.
Print it using supports for the notch at the bottom.
