After using the Tiny CNC that I made back in January for a while I've been wanting to improve it and make it more rigid. The natural next step for that router would have been to machine the plastic parts in aluminium but I was sure that the rods and bearings were way more important in terms of rigidity so I set myself to redesign it using linear rails. In the end I started the design from scratch and every single 3D printed part in it is new. I've tried to keep it as compatible as possible with the hardware of the MKI just in case those who got the files for it can switch to this new design.

In this new version there's also more clearance for stock, up to 85 mm and more usable Z travel as it can move up to 60 mm. The vacuum hose adapter of the MKI was taking a lot of usable stock clearance so I've designed a new retractable one that mounts on the side.

This one is clearly more rigid and can be pushed a lot to machine faster and better parts and I'm pretty happy with the final design.

As always I'd love to read your thoughts down below. Enjoy and thanks!!
