Tool Holder for the Dremel Pillar Drill (Precision Drill Press) you can find at:
https://www.printables.com/model/170838-dremel-pillar-drill-precision-drill-press
This bolts onto the main pillar (at the top so you don't have to strip the drill press down) and has recesses for 5.5 mm and 7 mm sockets ( for the M3 and M4 nuts) and holes for the appropriate hex keys.
Regards, Paul.
