I'm mounting a Nebula camera to the X gantry and it would “interact” with the tools if they were mounted on the right side. I flipped the original around so it could mount on the left side. I then borrowed an element from another holder to have a spot for the included USB drive.
The author remixed this model.
It's been flipped around to mount on the left side and has a cup/slot added to accommodate the USB drive.
