This is a tool tray designed for the Elegoo CC that mounts to the Spool side of the unit. This does Not use magnets but uses two of the CC's side panel screws to mount it. Longer screws are not needed.

Note: This is an original design and Not a remix but some of the inspiration for this came from the model designed by @Keina_943883 - Elegoo Centauri Carbon Toolrack by Keina | Download free STL model | Printables.com

I have implemented holders for two sets of bed screws, two USB thumb drive holders, a divider in the square storage compartment, holders for two nozzle cleaning rods, storage for two CC silicone cleaning pads and a holder for the official Elegoo scraper. 

I designed a middle riser with a chamfer at the bottom for the scraper storage to slide in upwards and therefore keep the blade pointed downwards.

I have uploaded two variants of the model - one with the “Centauri” text, and one without.

** Note: I have updated the STL files. I modified them for more support on the left edge of the Scraper holder and also pushed out the left and right sides to be flush with the edges.
