Zeiss Ikon-Contax spool remix

This is a remake of the very fine spool made by bingusmegaballs on thingiverse. I've copied it as well as I could, added an extra slot and tooth for grabbing the film, and split it into two parts for easy printing. I adjusted the dimensions to work well on the Zeiss Ikon Tenax I and Tenax II. 

Supports are suggested. The top ¾ of the spool needs no support, so block any there. 

Print the two parts vertically as shown in the image, then snap the upper flange onto the shaft. A small amount of glue will keep it in place. 

Re-modeled in Fusion to permit breaking into pieces for a 2-piece print with minimal supports. I've included the fusion model. Most of the model is at 10x scale (a scale is included in the timeline). Adjusted for Zeiss-Ikon drive dimensions.
