This is a new pen based on Twist Retractable Ballpoint Pen A. Because the spring in the “Twist Retractable Ballpoint Pen A” is a little tricky to print and remove support, so I made a new one. This pen's spring is separated from the body, so it's easier to print and remove support than Twist Retractable Ballpoint Pen A. It can use Zebra JF or Pilot LP3RF refill and may be capable of other brands of refill, you can add comments if it's possible.

The Nut part has 3 versions: “Nut-2Colors”, "Nut-Monochrome", "And Nut-Blank", so you can choose whether to use my logo or not. The logo"FAND" means “FANDESIGN”. That's the logo of my studio.

The recommended filament to print the body is BambuLabs PLA-CF , The Spring is Bambulabs PLA Tough , Because I tried to print the spring with PLA-CF, but it's more fragile than PLA Tough, ESUN's PLA+ is another choice.
