This is a version of my AMS lite spool holder wall mount (https://makerworld.com/en/models/214994#profileId-23424) that I've modified to take larger spools of filament like eSun 3kg and others.

The AMS lite holder doesn't go all the way through the spool center but it holds the spool perfectly well. I've printed over 20 spools of eSun 3kg and not had any issues.

This wall bracket holds an AMS Lite spool holder and enables you to easily hang spools on the wall, with easy and convenient access to change spools. The AMS lite spool holders have a mechanical clutch that retracts the filament a little when the unload process is running.

The AMS Spool Holders can be purchased individually from the Bambu Labs store: https://store.bambulab.com/en-nz/collections/spare-parts-for-ams-lite/products/ams-lite-rotary-spool-holder . The wall mount can be hung in any orientation but you need the correct AMS Spool holder Green unspools anti clockwise, the Yellow variant unspools clockwise.

You'll need to purchase PC4 M10 connectors to clip in PTFE tube. I got mine from AliExpress: https://www.aliexpress.com/item/1005005129845161.html
