About this 3D model
Kossel Effector where I added a fitting to attach the RepRapWorld 1/8" BST pneufit Bowden adapter. The hole under is 16mm dia to accomodate a J-Head. After printing my previous version, I realized that the dome was getting in the way. So here it is redone, with the thread embedded in the Kossel effector from jcrocholl (https://github.com/jcrocholl/kossel/). This works out very well - screw in the pneufit while it is still hot preferably.
