HSW Rolling Spool Holder (6000Z bearings)

This rolling spool holder for the Honeycomb Storage Wall is based on (and compatible with) the Ender 3 S1 Pro spool holder.

Required Hardware

• 2x 6000Z bearings (that is ID 10mm x OD 26mm x W 8mm), ABEC 1 is sufficient. Printed bearings might also work
• 2x M4 screws with a maximum length of ~16.5mm, longer screws preferred to increase strength

Alternatively you can use your original Ender 3 S1 Pro spool holder. In that case you only have to print the HSW insert cap.

Printing Instructions

I have successfully printed the model in PLA using a 0.4 nozzle and 0.2mm layer height with the following changes to the standard profile:

HSW insert cap: Designed to be printed without any supports. If you have issues with bed adhesion, use a brim. Use the recommended settings for HSW inserts (i.e. perimeters/walls: 4, infill: 20%).

Tube: Use random seam position to avoid getting a small bump every rotation. Additionally turn on scarf joint seams if you are using OrcaSlicer. If you have difficulties with bed adhesion, use a brim.

Cap: Standard settings work fine.

Outer shaft: If you have difficulties with bed adhesion, use a brim.

Inner shaft: This is a thin load bearing part, so make sure to use 6 perimeters/walls and 6 top/bottom layers (= 1.2 mm thickness). Use a high-strength material if possible.

⚠ Caution: Using these recommendations this part should hold a 1kg spool with ease. Please note that PLA creeps under load and I have not done any tests to see if it holds up long-term.
