This is a remix of the AD5X caddy from MakerWorld (https://makerworld.com/en/models/1953800-ad5x-tool-holder?from=search#profileId-2120040). Although it's not built on the same body frame, I used the measurements of the hanger and added some extra supports connecting it to the body. I opened up the face to allow some minor storage as well as having some drop in storage at the top. The large hole fits the standard Flashforge plate adhesive, but have not tried any other brands.
