Parametric Sheet Film Spool (4x5 and 9x12 by default)
Description
This is a highly parametric film spool ment to be customized to fit your tank and film you want to develope. IMPORTANT: This design needs an inner tube (the one in the tank) to be put on, it will not work without it! Just adapt the parameters in openSCAD to fit your tank and tube! Detailed descriptions on the parameters and what they change are commented in the SCAD file! The .stl files are sample exports: - Top, Bottom and Mid together will work for 9x12 film - Top, Bottom, Mid and SecondMid together will work for 4x5 (obviously it is also possible to adapt the length of the Mid part to fit every desired length but with two mid parts you have a flexbible design that can be used for both film types while reducing printing time) Depending on how your tank is build and how big it is it might be necessary to use the alternative version of AltTop and AltBottom that have a raised middle section. The version I printed fits an AP Compact Developing tank (600ml) and its inner tube
