I wanted a spool to mount a roll of filament onto the Honeycomb storage wall found on printables (https://www.printables.com/model/152592-honeycomb-storage-wall), but I wanted something that would support a heavier spool, have bearings for smoother movement, and still be relatively fast to print and use.

While it is well supported with just the HSW inserts, I have left holes in the mounting bracket to secure it via screws if necessary.

This model uses the following hardware, most of which is easy to find or even just have around.:

The rear mount filament spool which was supplied by Bambu Labs with the printer.

Two 8mm*22mm*7mm bearings (608xzz) - https://www.amazon.com/gp/product/B07FDYTJS5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Two M5x6x7mm Brass Heat Set Inserts - I prefer the inserts that have threading going in opposite directions, like the ones in this set here - https://a.co/d/j0WuIFV

Two M5x16 socket head cap screws - https://a.co/d/3Or34X7

Two M3x16 socket head cap screws - https://a.co/d/clZpyoe

Two M3 hex nuts - https://a.co/d/ig1YXdk

Bambulab parts are show in green below.  Amazon or AliExpress parts are shown in red below.

All grey parts are printed.

Assembly Instructions:

Step 1 - Use the Bambu Labs supplied spool holder, in the orientation as shown.

Step 2 - Place the printed HSW-Support Bracket part under the metal spool holder.  There are small grooves on the printed piece which fit perfectly into the rear section.

Step 3 - Using a soldering iron, set the M5*6*7mm threaded inserts into the HSW-Spool Mount, as shown in the before and after below.

Allow the heat inserts to cool for at least 5 minutes before moving forward.  I've set the inserts in the rear of the mount to provide more stability and strength.

Step 4 - Align the metal bracket, the HSW-Support Bracket, and the HSW-Spool Mount.  Secure the pieces together using a M5x16 screw.

Step 5 - Align the HSW-Axle holder on the metal bracket and secure using M3x16 screws and M3 nuts

Step 6 - Attach bearings on HSW-Axle

Step 7 - Place Axle in Holder

Step 8 - Mount system on HSW
