Epson Interactive Pen Collar

This is a repalcement for the black plastic collar that fits on the end of the following Epson pens (it is NOT available as a spare part and is ALWAYS getting broken)

     Interactive Pen A - Orange   Model: V12H773010
     Interactive Pen B - Blue        Model: V12H774010

Made with Fusion 360 and sadly hacked with Tinkercad. I was able to get the lower, thread perfectly done in F360 but could not for the life of 

me do so with the upper larger diameter thread. I ‘think’ a 10.5mm ISO would work but that does'nt exist in F360, or possibly at all

Works perfectly for me, but your mileage may vary. Try increasing/decreasing the % in your slicer
