[V3.1] Filament Holder 1/2/3/4KG Filament Spool Holder

The content uses translation and may not be entirely accurate:

Yes, version 3.1 has been updated to reduce the rate of partial print failures.

This accessory is currently undergoing beta testing. A preview is available, however, I cannot guarantee its efficacy.

Based on testing, the following recommended filament weights are suggested to mitigate potential impacts on print quality:

• A1 series with AMS Lite: Loading filament exceeding 3kg is not recommended.
• P1/X1 series: Loading filament exceeding 3kg is not recommended; the absolute maximum is 3-4kg.
• A1 series without AMS Lite: Loading filament exceeding 2kg is not recommended; the absolute maximum is 3kg. When using consumables exceeding 1 kilogram, supplemental extruder cooling may be necessary; otherwise, normal printing may be impossible.

Random seams have been implemented to prevent excessive resistance during filament spool rotation. This helps maintain print quality, though it may subtly affect the aesthetics of some printed parts.

Instructions:

• This filament holder is designed for convenient replacement of various filament specifications.
• Both long and short accessories are available. The short version is optimized for lightweight filaments (0.2/0.25KG), while the long version accommodates most filaments. Feel free to assemble them according to your needs:
• # TODO

Printing the holder accessories:

• PETG or other robust materials are recommended.
• For high-stress components, horizontal printing is advisable to ensure sufficient strength.

Emergency printed alternative for 608 bearings:

• Each holder set requires four 608 metal bearings. If metal bearings are unavailable, the following model can be printed as an alternative, though performance may be diminished.
• Note that this alternative supports a maximum of 3KG of filament. For filaments exceeding 3KG, metal bearings are strongly recommended (2kg or less for the A1 series).

• When using a BambuLab printer to print PETG, select the file: tr_0.15_tt_0.15.stl
• This model is integrated into the 3MF slicing file. However, I must reiterate that this bearing model is not mine; copyright belongs to the original author.

Chinese Instructions:

Yes, version 3.1 has been updated, resolving issues causing spaghetti-like print failures with some accessories.

This accessory is undergoing beta testing. Early access is available, but performance is not guaranteed.

Testing indicates the following recommended filament weights to maintain print quality:

• A1 series with AMS Lite: Loading more than 3KG of filament is not recommended.
• P1/X1 series: Loading more than 3KG of filament is not recommended; the maximum is 3-4KG.
• A1 series without AMS Lite: Loading more than 2KG of filament is not recommended; the maximum is 3KG. When using more than 1 kilogram of filament, additional extruder cooling is recommended, otherwise, normal printing may be impossible.

We've incorporated random seams to prevent excessive resistance from concentrated filament spool rotation, thus improving print quality. This may, however, slightly compromise the aesthetics of some prints.

Instructions:

• This filament holder facilitates easy replacement of various filament sizes.
• Long and short versions are available. The short version is ideal for lightweight filaments (0.2/0.25KG), while the long version is suitable for most filaments. Assemble as needed:
• #TODO

Printing the holder accessories:

• PETG or other strong materials are recommended.
• For high-stress parts, horizontal printing is suggested for optimal strength.

Emergency 3D-printed alternative for 608 bearings:

• Each holder needs four 608 metal bearings. If unavailable, the following model can be used, although performance may be reduced.
• This alternative supports up to 3KG of filament. Above 3KG, metal bearings are strongly advised (2KG or less for the A1 series).

• For BambuLab printers printing PETG, use file: tr_0.15_tt_0.15.stl
• This model is included in the 3MF slicing file. However, I must emphasize that this bearing model is not mine; copyright belongs to the original creator.
