revised gear head extruder simple 1405

This thing was made with Tinkercad. Its a combination of printrbot's aluminum extruder and another thing I found. Made this is a solution to printrbot's gear head extruder that I have been having trouble with. I took this thing from Extruder Mount (Printrbot Gear Head) by Walter.
It worked but it's still a work in progress.
