A 5x2 Gridfinity tray for the Iwiss SN-2549 crimping tool.
Probably also fits:
as these seem to use the same chassis.
Versions available:
Half-height (3u) - the tool sits about 3mm proud of the top of the tray so you can't stack anything else on top of it.
Full-height (6u) and 4u - the top of the tool is flush with the surface of the box, so stacking should be possible (not tested!)
(The SN-2549 is for JST and DuPont connectors and crimps both parts of the contact at once.)

Used kennetek's model as the base - tool hole added!
