Your CNC spindle control gets the protection it needs with this dual relay board bumper. You get a simple, smart design that keeps your relay board safe from workshop impacts.
This bumper was born from real maker experience. The designer built it to protect a dual relay board controlling a Grbl-based CNC spindle. Two reinforced columns cradle your board so it stays in place during operation. The compact design fits tight workshop spaces without taking up valuable real estate.
You have full control over the design. The OpenSCAD source file comes with your order, so you can tweak dimensions, add features, or remix it for other projects. Licensed under GPLv3, so you own what you make.
