Adapter AMS Bambu Lab đa năng cho mini spool (200g/250g)

REVISION HISTORY

• 2023-07-19: v1 - Initial release
• 2023-10-19: v2 - Updated to address the flaws of the original design; now made to be modular.

________________

This is spool adapter for Bambu Lab AMS that can fit a wide range of 200g/250g mini spools. See illustration for sample 250g spools that can be accommodated.

Version 2 addresses the flaws of the original design where the spindle will break easily either by overtightening or by dropping the spool. This release now has the spindle printed separately from the spool, made wider and is now horizontally oriented for added strength.  

PROBLEM

• The Bambu Lab AMS cannot use 250g spools due to its small size
• Adapters for 250g spool currently available are designed for specific brand of spools therefore each spool needs an adapter printed

SOLUTION

Design an adapter for 250g spools that can be printed once and can be reused over and over catering to a wide variety of the mini spools.

The threaded hub design lets you spin the spool clockwise to tighten, counter clockwise to unlock, which makes the adapter super quick and easy to transfer to another mini spool!

WARNING / IMPORTANT NOTES

1. Printing profile - please make sure you print the spool with 4 or more walls for added strength.
2. Supports are NOT needed on any of the parts.
3. DO NOT OVERTIGHTEN as you might split the thread layers
4. Proper filament types. Ensure that you have properly calibrated your filament and that the layers strongly adhere. Otherwise, you risk delaminating the layers. DO NOT USE SILK AND MATTE FILAMENT as layer adhesion of these type of filaments are usually not strong enough for these types of applications.
