Cable insertion aid for textile sleeve

Hi everyone,

I was upgrading my Prusa MK3 to a MK3.5 and there it was: Step 16 Wraping the Textil sleeve.
Every time I have some trouble to wrap the sleeve to the Heatbeds cable.

So I created this time a little helping thing:

How to use:
Take the outer part and put the textile sleeve over it. Then take the inner part and put it over the cables.

Insert the inner part into the outer part

Hold the the start side and gently pull the helper to the other side

I was even surprised that it worked so well the first time I tried it out, 
I wasn't expecting that ㄟ(≧◇≦)ㄏ

Print Info
If you want to print this thing,
I recommenting to print the the parts upright with brim. The inner part need some supports at the tips of the wings.
