Anycubic i3 Mega spool holder (filament saver)

thingiverse

I've tweaked the original design to minimize filament usage while preserving its robustness. Additionally, I've incorporated a tiny opening into the filament guide, making it unnecessary to remove the filament from the extruder in order to attach the reel to the holder. Print with 0.2mm layer height and supports are not required. To enhance build plate adhesion, try positioning the model as shown in my images. It's a snug fit, so start by attaching the shorter end first and then carefully insert the longer end, using gentle pressure if needed.
