My mother gave me her Ihagee Exaka II without a takeup spool. Nobody ever seen it for years.

This thing works fine, but the base diameter was approximized and should be tuned. It would be a huge help if somebody with real spool would share the dimensions.

This is not an easy print. I used "cross" supports with 15% density "everywhere" and 0.15mm layer height. Oriented ith with flat side down.

Post-Printing =============

You may need to run a bottom pin hole with 4mm drill bit.

Files included:

v9: the last one i actually printed. It works but it is tricky to load film into the spool.

v12: all troubles with v9 are accounted for, but i didn't test it yet. Hard to make 36 shots with this monstrosity, you know...

How I Designed This

My first attempt was before 3D printing with a lathe. However i quckly realized that the task requires a lot of trial an error and a slot for the film must be very complicated to hold it properly. So i started experimenting. I also tried to calculate a proper circle length for a 35mm frame and exacta's spool rotation. This calculation turned out to be spot on.
