Here For The Long Haul!

I see what you mean but looks like tube will work slipped over the thicker splined part the flat head of the screwdriver will center itself inside the tube worth a try?Cheers. HD12 has 3mm slots, HD6 4.5. I'll come up with something serviceable.
Apologies for *s-word pics.
On second thought cut that thin part off and slot the bigger splined head will work with tube then.
