This tool was designed to pull a plastic shell through a silicone hose. It might also be handy for other usecases.
The inner diameter of the shell I use this tool for is 6.7mm. If the Internal Extractor is needed for a different shell size it can simply be scaled by changing the scale factor in the slicer using the following basic formula:
100/6.7*<YourInnerShellDiameter> = scalePercentFor example: If you want to pull a shell with an INNER diameter of 10mm:
100/6.7*10 = 149.25%Hint: Do not add extra clearances in the calculation. They are already there by design. If your shell has an inner diameter of 10mm, then 149.25% scaling will fit without any additional clearances.
