3D Pen Filament Spool

thingiverse

This is a filament spool for an Aerb Printing Intelligent 3D Pen with LCD Screen, Black, measuring 6.4x10.2x20 (available from Amazon). I was captivated by Starman63's original design, but unfortunately, it didn't work out for me - the spool was too large, the spool sides were too thin and "perforated" (the axle holes popped out like a postage stamp), the mount was too weak, the single mount fixing wasn't the right size for this particular pen and lacked robustness, requiring a wider offset to accommodate the power cable. I know it sounds like I'm criticizing Starman63's design, but I'm not - the fundamental concept is exactly what I'm aiming for - so thanks for the inspiration, Starman63! All four elements can be printed together seamlessly, in one go, without supports. Print the mount and cap on their backsides. Once you have the mount and cap created, you can print as many spools as you need or want. I've also uploaded STP files so you can modify any of the elements using your own CAD or design software. Good luck, and let me know how you're doing.
