Ender 3 V3 KE – Reinforced Rear Spool Mounting

This remix of the original side spool mount relocates the spool holder to the rear of the Ender 3 V3 KE. Since the mount is extended to reach behind the printer, the geometry has been reinforced to better withstand the pulling forces created by the longer lever arm.

Placing the spool at the back helps optimize space around the printer, improves filament feeding alignment, and makes the overall setup more compact.

The part can be printed in different orientations depending on user preference and printer setup. However, supports are always required regardless of the chosen orientation.

The model is easy to print and install, with no special hardware required beyond the screws already included with the printer.

Recommended print settings:

• Layer height: 0.2 mm
• Infill: 15–20%
• Supports: Tree
• Material: PLA or PETG
