Nintendo Switch and Klipper turbocharge Prusa MK3S to 8-minute Benchy

A Nintendo Switch, not a new mainboard or an expensive SBC, was the hardware that helped a Prusa MK3S cut a standard 3DBenchy from about 90 minutes to 8 minutes and 41 seconds. The speed jump came from Klipper, the open-source firmware stack that pushes motion planning onto a general-purpose computer while the printer’s microcontrollers handle the low-level work, and from Klipper’s input shaping and resonance-compensation tools, which are built to tame ringing and ghosting at higher speeds.

Cocoanix 3D Printing showed the result in a video titled Klipper on a Nintendo Switch Made My Prusa MK3S 10x Faster, and the headline number is hard to miss even for people used to aggressive tune-ups. Hackaday’s coverage put the same print in the neighborhood of 90 minutes down to just 8 minutes, which makes this less like a novelty demo and more like a direct attack on one of desktop printing’s oldest frustrations: waiting around for a single small part.

That matters because the machine involved was not a blank-slate experiment. The Prusa MK3S+ platform sits in the mainstream workhorse category, with a 250 x 210 x 210 mm build volume, the kind of printer many owners keep running long after newer models arrive. The whole appeal of this mod is that it did not require replacing the frame, rails, or hotend. It repurposed hardware many people would never think to connect to fabrication and asked a smarter firmware stack to do the heavy lifting instead.

The real question, though, is whether this is a trick worth copying. Compared with a normal Klipper setup on a small SBC, the Switch route looks cleverer than practical. It still depends on the same Klipper concepts that many hobbyists already use to raise speed and preserve quality, but it adds another layer of hardware hacking and a less conventional machine identity to the mix. If the goal is a reliable upgrade path for an older printer, a conventional SBC-based Klipper install will usually look simpler, more repeatable, and easier to support. If the goal is to squeeze maximum performance from spare electronics and prove a point about firmware, this is exactly the kind of hack that makes the hobby feel alive.

3DBenchy itself helps explain why the result landed so well. CreativeTools designed the model specifically for testing and calibrating 3D printers, and its public-domain release in February 2025 kept it firmly in circulation as the community’s favorite speed-and-quality yardstick. On that benchmark, the Switch-powered Prusa MK3S did more than shave off time. It showed how far an old workhorse can still go when the motion system, not the frame, is the part that gets rethought.
