This is hex bolt and nut opener. Adjustable, turner on the top. You have to turn this wrench by palm. Specialy where you can't reach usual wrench with long handle, but this wrench cna reach in narrrow place easily. 3d editable STEP files are attached. 3d printable stl attached in a file, you have to seperate them.

Sutable bolt and nut size is M12 to M24. Custom size and design possible, you have to contact with me for that.
