Keep your A1 mini running lean and mean! 🐝 I just uploaded a new Honeycomb Refill Spool specifically for those 74mm ID refills. The A1 mini’s spool holder can be picky with weight and balance, so I designed this to be as light as possible without sacrificing strength. The honeycomb pattern looks great in motion and saves a decent amount of filament on the print itself. Highlights: 74mm Inner Diameter Fast print: Optimized to get you back to your main projects quickly.
