HUB75 LED Matrix Mounting Frame for Two 128x64 Panels (3D Print STL + OpenSCAD)

A printable back frame that joins two 128x64 HUB75 panels into one rigid 128x128 square, sized for a Bambu A1-class bed.

Coming soon. It's built and waiting on a final check before it goes on sale. Planned price: $9.

Launch updates by email are coming soon.

Two 128x64 panels side by side don't hold a flat seam on their own. This frame prints in quadrants that fit a 256 mm bed and joins with straps. The vertical seam is kept solid because it is the only support for the middle of each 254 mm panel, and the horizontal seam keeps a cable channel.

It's listed as coming soon until its fit has been checked against real panels and documented with measured photos.
