【Lao Teng】New Machine Essential External Filament Spool Holder Axle Thickening Stabilizer for A1 Filament Spool, No Shaking, Smooth Rotation

=====Updated November 4, 2025=====

• Added a scaled-down A1 version to fit most third-party filament spools
• The scaled-down version's core diameter has been reduced from the original 54.4mm to 53.3mm, compatible with most third-party small-hole filament spools, including R3D

=====Initial Release Notes=====

【Note】

Before printing, please confirm if your A1 spool holder is the latest version (as shown below). Some users reported that older spool holders do not have holes, preventing the insertion of the retaining pin. It can still be used, but it will wobble. Of course, if you don't need it to be fixed, you can ignore this

• This is an optimization for the A1's built-in external filament spool holder
• The included external filament spool holder is too thin; when a filament spool is placed on it, the spool wobbles back and forth. During printing, as the feed rate changes, the entire spool swings like a pendulum
• This significantly increases the machine's instability and affects the final presentation of the printed part
• Therefore, I designed this spool shaft. Once installed on the holder, it will make the filament spool fit snugly and rotate smoothly
• If you print with official light gray PLA, the effect will be even better, just like the original

• Below is the installation tutorial (taking the A1 version as an example)
