Designed and ordered two custom Arduino Mega shields for a 3D printed RC tank build — one for the vehicle (motor control + accessories), one for the remote (stick inputs + toggle matrix + telemetry display).
Both are 2-layer designs. Top side has the components and signal routing, bottom is mostly ground plane with some power routing along the edges.
Spent a long time on this. Not a traditional 1/35 styrene build — but the design philosophy comes from the same place: armored panel detailing, modular accessory loadouts, surface finish, the look and feel of an "in-service" combat vehicle.
About 60cm long, 12kg, fully 3D printed FDM. Held together with screws into brass threaded inserts — no glue, no welding. Custom electronics inside make it actually drive under RC.
Modular loadouts include a front plow attachment, side skirts, quad missile pods, and twin turret barrels — designed so you can swap configurations the way the wargaming side of the hobby works. Paint scheme is industrial grey on black tracks, with brand markings on the hull.
I respect the craft this sub represents — the weathering work, photo-etch details, dioramas, the patience — and I'd genuinely love your eye on this kind of hybrid build. What works visually? What would you improve? Any scale modeling techniques you'd apply here?
Spent a lot of time designing this — 60cm long, fully 3D printed chassis, dual brushless motors with custom gear reduction, held together with screws and brass threaded inserts. No glue anywhere in the build. This is the moment in Episode 1 where the tracks finally moved on their own. The motors had been overheating for weeks, then torque was insufficient through two gearbox iterations, then the suspension nearly couldn't hold the 12kg weight. Three redesigns later, here we are. Full build breakdown on YouTube if anyone wants the engineering details (linked in comments because not sure if main post allows). Happy to answer questions about printing settings, motor specs, or the gear ratios.
