The thread is humming along smoothly and the cap is functioning perfectly. The parts are printed with a medium to high level of quality, but you may need to make some adjustments in the Autodesk files to get it working at low quality. This pen is designed specifically for the Pilot G2 refill, which can be found on eBay in packs of 10 or more, such as this one: https://www.ebay.com/itm/10pcs-Pilot-G-2-0-38-Roller-Ball-Pen-Only-Refill-Red-/361534983796. However, it's likely that other rollerball refills will also work - feel free to experiment and provide feedback!
