Moira Brown will give it to you and asks you to insert it in the mainframe of the RobCo Facility.
The insert piece does press fit into it, so you need to make sure your printer has good calibration.
All I had to go by was the black and white drawing from the Wiki. I think i did pretty well.
For somereason the photos don't show the right way up.
Both parts are fine details. The Widget I think I did .2mm layer, 25% infil and 0 shells.
The Widget inside since since it is only 1mm thick. I did .2mm Layer, 100% fill, and 0 shells. (It took 15 minutes to print the inside)
Once done, do a small amount of clean up around the single hole on the bottom of the inside, then just press it into the main body.
