Filament Side-feed System

The purpose of this system was to remove the factory top-mounted spool holder with a side-fed system, so that a dry box or other side spool setup can be used.
I have a Sidewinder X1 printer, but it works with standard v-slot gantry tubing (6 mm opening).

Key features:
• Utilizes the factory filament break sensor, but changes the mount to reduce drag
• Minimizes drag throughout the whole setup
• Keeps the system very low profile
• No modification of the X1 is required
• Prints can be mirrored for right hand or left hand feed direction
• Optimized parts kept as small as possible, and design for 3D printing (minimal supports)
• Can be used with other printers that use the same gantry support beams
