I loved Scotts Skadis mod for the Core One but wanted to free up space on the Skadis panel by placing a tool holder inside which holds most of the tools provided with the Core One, some nozzles, and more. This removes one print sheet slot, but I'll only ever need to store two sheets. I also found inserting print sheets to be a bit finicky, so I added guides and magnets to aid with sheet install and retainment.
Only additional hardware you'll need is eight 10x3mm magnets to retain the build plates and keep them from rattling. If you don't mind them moving around a little, then feel free to skip the magnets.
I designed the tool bar to be printed face down to obtain a nicer surface finish, especially when used with the textured sheet. Stock print profiles are fine, just need to paint support on the mounting tabs (2x) of the tool bar:

I'll only be outlining the build instructions unique to my remix - see Scott's original post for anything missing.


2. Glue (2x) 10x3mm magnets into each corner part, then insert guides:

3. Glue allen and torx supports on tool holder. Glue (2x) 10x3mm magnets into each side “rail” section and (2x) 6x3mm magnets into back of the toolbar. I provided a third 6x3 magnet hole on the toolbar in case you want extra strength, but I found only two were sufficient. Install toolbar onto guides. Keep in mind the correct guide orientations:


4. Install this assembly onto the hinge parts, attach Skadis panel, then insert everything into the Core One side panel. Done!
