Remixed from several designs. Kept the channels to keep Allen Keys in place, and the hole for the 0.4mm Nozzle included in the printer toolkit. Added a single hook for a scraper, and a glasses holder, because I unfortunately need glasses to see the smaller parts of prints up close and then inevitably lose my glasses in the clutter of my work space.
