Description

CARDBOARD SPOOL ADAPTER

Ensures a Secure and Stable Fit

Adaptive Mechanism to Accommodate 195 to 200 mm Spool Sizes

Handles Cardboard Expansion and Minor Deformations with Ease

Print Instructions & Recommendations

No support required.
Since the design has small dimensions to prevent jamming inside AMS, the following settings are highly recommended for clean and stable prints:
- Top Surface Pattern: Concentric
- Bottom Surface Pattern: Monotonic
- Internal Solid Infill Pattern: Rectilinear
- Wall Generator: Classic
- Detect Thin Wall: Disabled
Almost for all cardboard spools, printing the 3.5mm-thickness model would snap-on and lock. If it does not, try 3mm or 4mm models depending on the fitment.

Assembly Instructions

For easier installation, start by securing one edge first, then press down on it while installing the opposite side.
This adapter works with the majority of cardboard spools, and the following brands have been tested and confirmed by the community; if you have tried other spools, please share your feedback to help expand the list for everyone:
- Anycubic
- Creality
- ERYONE
- eSUN
- Inland (only with lid open)
- Overture
- Polymaker

Printed in PETG-Translucent Clear (was trying to use the end of my spool), used 3.5 profile Although it seems not very sturdy, minimalist, on purpose. I definitely wouldn't be rough with it. I tested it out on an ERYONE spool successfully to see how it works. It seems like it will work well. I'll be able to test with ESUNs soon and will update but from what I see it'll work the same way. Cool idea

The only thing I'd suggest is to give instructions that when using bigger spools, it creates gaps because of the stretching that occurs. I found it helped to equalize the gaps all around the spool to minimize the effect. When I first did it I didn't notice much and I'd created one large gap and two no-gap sections. IT rolled better with three small gaps instead. With one large gap it was much like hitting a pothole in the road when doing my test roll in my AMS.

Replying to @branrollins :

Thank you for this detailed feedback! I completely agree with you, having even gaps definitely makes it smoother. The design is still in its early stages, and I will continue refining it based on both feedback and my own experience. If you notice anything off or have any suggestions, they would be greatly appreciated!

Replying to @ERAVIA :

Printed Esun spool as well successfully. I am finding it's better to try and stagger the gaps as well. I happened to line up both sides so the gaps were the same on each side side which made it really bumpy, I rotated one of them a bit so they're not hitting at the same time and that helps. Hope that makes sense.

fit my polylite asa spool but did not work in the ams. it wouldn’t spin properly so it wouldn’t load

The designer has replied

@ERAVIA

Thank you for the feedback! Sorry to hear it did not work out. May I ask if the spool works with the AMS lid open, or does it not rotate at all? If it works with the lid open, it likely means the spool has a diameter larger than 200mm, causing it to get stuck inside the AMS. Unfortunately, in this case, the adapter may not be suitable for use with the AMS when the lid is closed. However, if it does not work at all, regardless of whether the lid is open or closed, it suggests that the rollers are not properly gripping the adapter. I have encountered this issue before and often resolve it by repositioning the spool on the rollers, giving it a slight rotation, or wiggling it gently to ensure it sits properly. If none of these solutions work, let me know, and we can try to identify the issue further. I hope this helps. Have a great day!

Replying to @ERAVIA :

It doesn't work at all unfortunately and I assumed (based on observation and the noise) that it was the rollers not spinning it as you suspect. I tried wiggling it around (front to back and side to side) and at one point it spun a bit but not enough to even make a full rotation before stopping again.

@ERAVIA

Replying to @russ_v :

Sorry to hear that as well. If it is not too much trouble, could you try the adapter with a different spool containing another type of filament or from a different brand? This would help us confirm if the issue is related to the adapter itself. Sometimes, the bent shape of the filament or excess friction can cause the rollers to stop, preventing the filament from loading properly. Additionally, please check that the gaps between the adapter arms around the spool ring are uniform. If the gaps accumulate unevenly at one arm, it could create a slight bump that might force the rollers above their threshold and interfere with proper rotation.

Works!

@ERAVIA

Thank you for the fast print and feedback! May I ask for which spools you have tested the adapter so far? I would like to include a list that shows which spools have been tested, and their compatibility with the profiles for reference. Thanks!

Two pieces were sticking together consistently but we're easy to break apart without damage

@ERAVIA

Thank you for printing! Sometimes that happens depending on printer calibrations, however as you pointed out, it can be broken apart easily.

Awesome print! works incredibly well on Polymaker and Overtune cardboard spools.

@ERAVIA

Well, thank you so much! I am happy to see it works. Also, appreciated that you shared the test results, added to the list of tested spools! Happy printing! If encounter any issues in the long run, please let me know so that we can address it!

This looks promising, not to say interesting. Printed fine with PETG which is a bit more elastic than PETG. I adjusted some settings like enabled "avoid crossing walls", disabled "detect narrow internal solid infill".

The designer has replied

@ERAVIA

Thank you for the support! As long as those settings worked out, that is great. I will give it a try with those settings today. The published settings are there to ensure the infill and surface patterns contribute to the elasticity of the adapter. Thanks again!

@p0wertiger

Replying to @ERAVIA :

Avoid crossing walls helps reducing stringing which is significant with PETG. The second option causes the solid infill area in some places to be printed as concentric instead of rectilinear, disabling it gave more predictable results.

Thank you for the insights! Definitely will make use of this.

Replying to @ERAVIA :

It was good but sometimes it felt out.

@ERAVIA

Replying to @Miguel1234 :

I see. Could it be possible that your spool is thicker or slimmer than the adapter so that the edges are unable to lock? There is also 3mm and 4mm thickness profiles you can print depending on the thickness of your spool. Let me know how it goes. Thanks!

Sits too loosely on the spool edge

@ERAVIA

Thank you for your message This has been translated from English, so I hope the content was understood correctly The adapter is available in three versions to accommodate different spool rim thicknesses If the spool rim is thicker than the adapter, the 4 mm profile might be a better fit If the spool rim is thinner than the adapter, the 3 mm profile would likely be a better choice These variations have been provided to ensure a proper fit for various spools Should you have further questions, please do not hesitate to contact me

These are awesome! and the little squiggles act as an integrated filament clip!

@ERAVIA

Thank you for the feedback! Actually, there will be a built-in filament clip soon but it is great you have already utilized the model as is for that! It is a surprise for me too!
