I did already rant about the toolhead-mount on the Thing-o-Matic.
As predicted the 2 glued connections on the right and left side did come apart after a bit of traveling, shaking, heating up and cooling down.
Luckily in the google group Aaron pointed out that someone has already designed a replacement that eliminated this issue.
So I just retrofitted my TOM here "in the field" at Gullasch Programmier Nacht.
This thing is more then just a tight fit.
It's too tight and not tappered. So I had to use the battery operated Dremel Stylus on it quite a bit to make it "just" a snug fit.
