Hello 3D Printing Enthusiasts!
If you are considering or already own the Tronxy X1 3D printer, you need a filament Spool Holder. The available options may be suitable for you. Some of the spool holder designs are difficult to print on the X1 or not robust enough for long-term use. To resolve this, I have developed a Modular Spool Holder for the X1. The design works with the X1’s size limitations and is less vulnerable to failure due to load forces than the other designs I have tried.
Supplies
You will need a 3D printer. The files that have been supplied include .stl files, which are compatible with most slicing software applications, .3mf files, which work with the Cura slicer software, and .gcode files, which are ready to print on the Tronxy X1 and other 3D printers.
You will need the following hardware:
- 1 - 175 mm length of M4 threaded rod.
- 1 - 145 mm length of M4 threaded rod.
- 4 - M4 nuts
- 4 - M4 washers
- 4 - M4 lock washers.
- 2 - M5 screws

Print the Endstop and 7 Bricks at 20%. Cleaning the prints is easier if you use the "tree" setting for supports.
Print the Base and one Brick at 60% infill. Mark this brick with a sharpie to differentiate it from the other Bricks.
The Base and Vertical Beam
Start with the base and stack 4 bricks together. Place the marked Brick on top of the stack. The tabs on the brick fit into the slots of the next brick or the rectangular holes in the base. Insert a 175 mm length of threaded rod through one of the sets of holes. Put a washer, lock washer, and nut on each end of the threaded rod and hand tighten. If you choose to use wrenches be very careful to tighten them only as much is needed to hold the pieces together. Over-tightening will damage the printed components.
Stack and Attach the Horizontal Beam
Next, take the Endstop and stack three bricks on it. Make sure the sloped part of the Endstop faces toward the stack. Insert a 145 mm length of threaded rod into the holes that will not intersect the vertical threaded rod when you make that 90° connection. Insert the end of the threaded rod into the unobstructed hole of the top brick of the vertical stack. Add washers, lock washers, and nuts. Hand-tighten the nuts to complete assembly.
Mount the Modular Spool Holder on the Tronxy X1

Use the M5 screws to mount the Modular Spool Holder onto the top of the z-axis extruded profile. Use the provided tapped holes. Next, put the filament spool onto the horizontal beam of the spool holder.
Watch the video below for a demonstration of the assembly and mounting process.
