YAMS - Yet Another Mini Spool

YAMS – Yet Another Mini Spool

YAMS is a compact, threaded mini spool designed for small amounts of filament, wire, string, or other flexible materials. The two halves screw together smoothly and securely using an integrated thread system — this is the main feature of the design. The thread engages cleanly, tightens easily, and holds firmly in use.

The spool is available in two diameter versions:

• 120 mm diameter × 31 mm width

• 109 mm diameter × 31 mm width

The 109 mm version holds approximately 111 g of filament (around 30–35 meters depending on material and diameter).

Hole diameter - 53 mm, suitable for any holders, fasteners and automatic filament change systems!

There is also a small locking hole to secure the filament end when starting a winding.

Customizable Pattern Core

YAMS supports a modifier-based pattern system that allows you to create a visible cutout design in the spool body.

Print faster! The pattern generated by the slicer is printed much faster than the pre-cut one

Included files:

• Ready-to-print 3MF project with all slicer settings preconfigured

• *modifier files for manual customization

The modifier creates a patterned cutout in the side walls.
The internal pattern directly affects the visual design.

The modifier also contains a small rectangular solid area that remains unpatterned — this can be used for:

• a sticker

• labeling

• writing with a marker

How to Use the Modifier

1. Add the *modifier file as a modifier mesh in your slicer.

2. Disable top and bottom solid layers for the modifier.

3. Keep:

   • External perimeters

   • Infill only

Recommended pattern settings:

• Honeycomb infill

• 2 wall lines (infill line thickness = 2 lines)

• 30% infill density

These settings are already configured in the provided 3MF file.

Printing Recommendations

• No supports required

• 0.2 mm layer height recommended

• 3 perimeters for strong threads

• Print threads at moderate speed for best surface quality

Materials:

• PLA for general use

• PETG / ABS if higher durability is required

Key Features

• Very smooth, precise threaded connection

• Strong mechanical locking

• Two size options (109 mm / 120 mm)

• Pattern-customizable side walls
