Description

Updated 12/30/2023: Reworked threads to allow the two halves to close fully.

Update: Due to dimensional differences with each half, I have uploaded a corrected file.

This assembly will allow you to use the 250kg mini spools in your AMS. Just use the supplied bushings on each side and screw together.

You can also use this on full size filament spool with at least a 51mm id.

I love it. I have found instead of using the spacers I just turn one side backwards and seems to work just fine.

@miru8112

I really don't know how to feel about this... First both sides have different dimensions. Thats been said before, but then there is the situation that the one side does NOT completely screw into the other. There is a gap inside the spool, whis is annoying. You said that you updated the spools, but which side tit you update? I don't want to reprint both. Also, can you please do the winding completely through?

This spool assembly was designed for the use of mini spools in the AMS. I did not feel that the space between the pieces mattered. How are you using this? Are you rewinding spools on this? I will check to see what side I changed, in the meantime I will rework the threads and upload new file.

@bigdog7

I changed the female threaded side to match the other. One was 198mm the other was 202. Both match at 202mm. I am changing the thread now distance now and will upload shortly.

Replying to @bigdog7 :

Hey mate, No, I don't rewind on it, I just wedge my mini spools in it, like you do on your picture. However, I am using AMOLEN Spools, which don't work with your rings, so I had to modify some things. Even after modifying I had a huge crash last night as filament tangled itself up between your big spool and my small spool. I used a setup where I use PETG for supports and PLA (AMOLEN) for printing. This setup makes te PLA unload a lot. Obviously it doesn't work well if there is space between the small spool and the adapter, as this cused the fail. Has nothing to do with your design, just the interplay of my described setup... The "bushings" as you call them (I'm not a native speaker), the two spacers, proved to be a problem to me. I need to make your spool a way where it sits flush to my minispool to prevent further complications.

je ne sais pas si c’est pour une certaine bobine mais les deux rouleaux n’ont pas le même diamètre donc c’est croche dans l’ams et on ne peut le serrer fort pour retenir la bobine de 250g donc ça va quand tu imprimes avec une seule couleur et que le filament ne fait qu’entrer mais quand vient le temps de ressortir, la bobine ne tourne pas avec l’ams et le filament ne s’enroule pas sur la petite bobine

Précisément la problème!

works perfectly for adapting inland cardboard spools for use in AMS.

Nice! Can you give me a boost! Thanks

@Charlie75

Why is each side a different size? One side is 202 x 202 and the other is 197.956 x 197.978

@rmettscher

I am having this very same problem. I really like the design but this is strange.

@lwatton

Have you considered making this as the base spool holder (or with a smaller centre) then creating slide on centre adapters to suit whatever the size of spools you use?. Or print outer sides separately to the centre spindle then you can print the outer's reasonably quickly as they are low. Then print the centres together as a batch of 4,6 whatever. just a thought, not a criticism.

The designer has replied

@bigdog7

I will check that out thanks!

@lwatton

Replying to @bigdog7 :

The other option that may work is to print the sides with circles of fine teeth then just clamp the cardboard spool sides with the teeth no real centre adapter just a centre spindle/bolt using the circles of teeth as a guide (perhaps printing a ruler from centre to edge) to accurately centre the spool.

@bigdog7

I did the small diameter spool as an afterthought. I still had a couple of the small spools left but I thought most people shied away from them. I have had some people tell me that my regular sized spool adapter did not fit their spools because of a smaller diameter. I just told them to use the small spool adapter. I will revisit this as soon as I have time. Thanks
