I developed a swirl-twirl pen that uses a Caran d'Ache Goliath refill. My goal was to create a beautiful, high-quality ballpoint pen at a relatively low price. It also makes a great fidget pen.
To achieve a better surface, you can also reduce the layer height.The two shafts are printed inside each other and can be shaken apart after printing.The threaded cap should be printed separately next to it, otherwise the filament will connect.
Easy to print - no support required.
