This is a holder for the Wera screwdrivers that are great for 3d printers. They mount to 3030 extruded aluminum.
Similar to my holders for the titanium screwdrivers but with a smaller hole for the wera ball end hex screwdrivers.
I purchased my set years ago, one of them has the number 118092 on it. So searching for “Wera 118092” should bring up something close.
