Replacement tesa dispenser frame

The original tesa dispenser has the tendency to break apart in the back and flex to the sides away, making it a very fragile construction.I redesigned the rollerassembly using the original blade. You can simply take the old blade off and put it in the main body of the print. The tesaspool has to be put onto the insert and put into the according notch on the frame. The spool shoud have a friction fit, if it dosent, you can put a strip of tesa around it, then it shoud fit.The frame needs no supports, only the spoolholder needs some.
