Ender 3 series tool holder improved

remixed my remix of a popular tool holder.
changes from v12:
-added raised bolster so calipers don't auto-on d/t vibration
-added sloped chamfer on xacto blade opening
-added fillet on allen wrench openings
-added improved chamfer on scraper slot
-glue stick cap up=pull free; cap down=cap stays

use buildplate supports

edit: my apologies, v8 somehow the slot for the Xacto blade was filled in.
v12:
-fixed xacto blade slot
-added more clearance on the microSDs
-spread the hex keys apart a little
-wider slope on the scraper slot
