TecBoss Power Socket Holder

3D pens are handy for repairing 3D prints, until they break. Then you may need a 3D printer to fix your pen.
The TecBoss took one too many tumbles from the cart, and the piece that holds the power adapter in the black part of the top snapped off. Fortunately, a small flat bladed screwdriver will allow you to nudge the tab that holds it in place and lift it gently to look inside. There's not a lot of wire, so don't yank it out, just raise it up high enough to see the screw that holds it in place (see pictures).
Using a small screwdriver, gently unscrew the old power adapter holder, and remove it. Print out a new one, set the power adapter into the top (it's rectangular),
Feed the screw into the printed part, find the old screw hole and fit the new part so it will hold the power connector in place. Don't over-tighten.
Once we got it back together it worked like a charm.
