SUNLU for AMS with Silica or Weight

I am a loyal user of SUNLU filaments, in particular my preference is for PETG and PLA+, which I find very performant and with an excellent value for money.

The problem is SUNLU's new reusable spools, which are aesthetically pleasing, but don't get along with the AMS because of their small size.

Obviously I started like everyone else to use the various adapters that many creators have uploaded to Makerworld to increase the diameter of the spool, allowing them to work inside the AMS.

However, the problem remained of the weight of the roll at the end of the filament and the need to insert desiccant to reduce moisture inside the AMS.

So I thought of designing an adapter that would allow you to combine the various functions.

I have done many prototypes and I have tested the project that I present to you for a long time, I can tell that I have just finished the third print with over 400 filament changes without errors of any kind 😉

Part A has a container that can be filled with both silica or weights (for this I use fishing leads, as you will see in pictures), which can be replaced with the desiccant when the spool becomes too light and would tend to jump inside the AMS.

The assembly is obtained by inserting the spool into part A by making the filament data label fit with the wider window of part A. 
 

On the opposite side of the label there is a relief that will fit into the spool window and on the margins there are three little teeth that must be embedded on the circumference of the roll.    

The next step will possibly be to fill the container with the desiccant, dissolved in balls or contained in bags, or with some weight that we deem necessary.

At this point you can insert part B and rotate it counterclockwise until the visible windows match. You will hear a small click that informs us that the closure has occurred.

Also in part B there are three teeth that will fit on the circumference of the spool and make the adapter absolutely stable.

At this point it can be inserted into the AMS and it will work perfectly.

For disassembly it will be necessary to rotate part B clockwise and release the three teeth from the edge of the spool.

I have also added a knob to the project that can be useful to facilitate this maneuver, as it multiplies the force exerted to unscrew or invite part B on part A.

I hope this work of mine will be useful to the many who, like me, really appreciate the SUNLU material and want to avoid those AMS errors that make a long print an almost endless job!
