I've been working on a modular and scalable corexy design called the SolidCore for over a year now. The plan is to have a platform or ecosystem of parts that can be used on any 3d printer that uses 2020 frame extrusion. The original motor plate had a 20mm cut out to seat in the corner of the frame. One of the problems I ran into was that many of the frames use square corner brackets that don't have the clearance needed in order to mount the motor plate mount. So I'm designing a motor mount that mounts within the inside of the frame instead of on top of the frame.


Before

The old SolidCore motor and idler mounts worked great but limited the number of frame extrusion bracket options.


Many of the new frame brackets or connectors use an endcap style connector.
After


Frame Rigidity

I was planning on scaling up to a 3030 mm frame extrusion on the next larger corexy build. With the components mounting within the frame adds more rigidity to the frame.
