Creality Space Pi Stand

If the bed fits the plate model horizontally it would be perfectly printed without supports.

On my Ender 3 V3 SE I've printed it on a side with supports.

There is no precision compensation gaps applied between legs and plate in the model. This is done intentionally to assemble it tightly without glue. Possibly you'll need to perform some pressure or ever use a small hammer (be tender ;-)).

I've used just the shape idea fully re-drawed the model from scratch.
It's designed to stand nearby to the printer inside a box where is no way to plug it to a wall.
