The router used by maslow needs to have a diameter of 69mm and a length of not less than 110mm. When you choose a router, it can be used as long as its diameter does not exceed 69mm and its length is approximately 100mm.
If your router is smaller than 69mm*100mm, I suggest you use 3D printing to make a casing for it, like this.
I added some cutouts to the casing, hoping this would help dissipate heat from the router.
Even if you don’t have a 3D printer, you can still find a local 3D printing service provider to make it for you. Usually the price of such a shell is not too high.
As for the printed model files, you don’t even need professional modeling software, you can just use orcaslicer to create them. If you need help in this regard, I would like to help you to the best of my ability and help you create the model file of the shell in my free time. It is recommended to use high-temperature resistant materials such as ABS, because the router may have a higher temperature when running for a long time.
I made this model using shapr3D, I will attach the step file for reference.
Thingiverse supports parametric models (I just discovered that this morning). I don’t know how to create them but if someone else does, it would be a simple solution where anyone could input HxWxL parameters and get the right model to print for their particular router.
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.
