I created a parametric model so that anyone can generate a shell file suitable for their own router by modifying a few parameters.
The last two parameters are suitable for the case where the router handle part has two diameters. If not, please keep router_height2 at zero and only need to modify the first two parameters.
Please note that ABS has a high shrinkage rate. Please enlarge the parameters appropriately. If the shell is difficult to install, you can moderately heat it to facilitate the insertion of the router.
