A friend asked me to build this based on a metal example online (25mm, 62mm and 320mm long). As the tool is screwed onto the stick it is open for other tools to be added in the future or create some yourself. Show us what you build and added.
Easy and fast printing. Support only needed for the sticks. Carefully remove the support from the inner thread.
I printed it also without support for the inner thread and it works fine. In order to do this you need a slicer that can manually add or remove support.
