this gear was made so i can use my bolt that was hobbed at 26 mm from under the head.
also included is a small gear with space for a nylock nut, and thicker walls.
both of these are printed and do work.
the gears are drop in replacements for either (or both) of the gears for the 2 things linked as remixed from.
i have also modified the SCAD to allow for customisation of a few extra things.
a. allows for a extra lide wall in the small gear. this works by adding what you specify for the variable to the wall that is already generated.
b. allows the rotation of the arrow decoration.
they are both quick and dirty mods, but they work.
also attached is the prerequisites for the scad, download the zip for those
