Serger wish -
 

I wish that there was a compartment in or on the machine to hold the wrench needed for the needle set screws. Those attachment boxes seem to wander off or get lost!

Doesn't it have a compartment under the spool holder? You might be able to glue velcro on the wrench and a small piece on the serger. There used to be clips to hold pens that would stick to the machine. Here's some:

Mine uses a regular screwdriver

My serger is a very old serger and when you open the side door there is a place for some of the tools. Take a look and see if there is a place where you can click the tools in. Mine doesn't have an empty space it has click spots to click them in.

I bought some used ones - and some of the tools are missing.

I have a compartment under the plate to the left of the mechanism.

I use a suction-cup hook on the end of my serger to hold my snips. Does your wrench have a hole in the end to hang it on a hook?

I have one and it has storage that slides out right under the thread spools
