3D Printable Brushless Gearbox Housing & 6mm Twist Hub

$3 is a suggested donation price. Purchases help to fund my future robotics projects and videos, and the development of future products. However, if you do not have the cash to spare, to download for free, simply enter the discount code FREEDOWNLOADGB at checkout.

This is a CAD design file, not a physical product, of the Beetleweight Brushless gearbox I designed for Division. It can be modified to your heart's content and easily adapted to other robot designs. This upgraded V2 version uses 3X #6 plastite screws to mount and has a better, thicker washer to retain the wheels.

All parts are listed in the CAD assembly and the Bill of Materials.

Recommendations & Use

I strongly recommend printing the gearbox housing in CF-Nylon, but if you want to use other materials, your mileage may vary. If you cannot print CF-Nylon at home, you might be able to modify your 3D printer to do so (at your own risk). I also offer a 3D printing service and can print the part needed on demand!

The full Bill of Materials is available here.

V1 had 2X M3 hex nut inserts 17mm apart just like Servocity Econ gearmotors, and it's a drop-in replacement for those if you have room. V1 inside Division fought four battles at the November 2020 Norwalk Havoc event without any failures besides the print splitting behind those hex nuts, hence the design change. They still were able to drive perfectly with that damage.

More Info

This product is just a CAD model (Computer-Aided Design) - 3D design files that can aid in constructing a robot or part - and not an actual physical product. Nothing will be shipped to you after your purchase. As this must be fabricated by the user with your own 3D printer, we cannot guarantee the design will work with the tolerances of your equipment. Adjustments might be needed for smooth operation. 

The design is available in pretty much every CAD format under the sun and will work with any CAD program that accepts the universal STEP or SAT filetypes (including Solidworks), plus it is native in Autodesk Fusion 360.
