مفتاح إغلاق خلفي AeroTech 18-29mm RMS - 91295

Been using this wrench for a few builds now, and the 3D printed grip makes tightening the aft closure much easier than using pliers. Saves my knuckles from those awkward angles inside the motor tube.

Once I got the hang of which end fits which aft closure, this wrench made swapping out casings noticeably faster. The layer lines on the 3D print are clean and it hasn't cracked under moderate torque.

The 3D printed material feels surprisingly sturdy in hand, and it grips the aft closures perfectly without slipping. Snug on the 18mm hardware and also works great with the 29/40-120—saved me from stripping another closure.
