View Full Version : THING Printable Cube 3 Filament (re)Winder

02-27-2017, 01:09 AM


I made a filament winder to refill cube 3 cartridge ,, very easy to use you can download it at the following link :


Please if some one can helping me to describe this my English is not good enough

A video of it in action @chaman? would be even better :D

03-02-2017, 11:49 PM
Done ,, new video added :D

Alright now that we know how it works, who's up to mod it to attach a drill to it lol

03-03-2017, 09:19 AM
That's fantastic @chaman! Thanks for sharing the vid!!

Now for v2 add a winder tilt'er so the small filament path gets left and right on every turn! hah

Bravo! Bravo!

Good job Would this work on the CubePro Cartridges and has someone modded this for that purpose?

Can you post up some images of what you are looking at with the cube pro carts?

I did a quick google search on how to take apart the pro's cartridge and found this site. https://miller3dprinting.com/fix-cubepro-cubex-cartridge/

If they can be disassembled as it says on this site then you shouldn't have too much trouble putting new filament in. I think we've only had one other person in the forums who has a pro, the rest of us have cube 3's so you will be doing things most of us haven't done. By the looks of the inside of the cartridge, this looks like it can be used to re-spool.

RFID chip huh...

Have you made this yet, Bo?

I still think an intermediate step would be good.
De-spool onto an interim large spool to make sure the OD of the source spool will be on the outside of the 3DS spool.
in short, you pull off the 1/3kg onto a nice big spool so no filament is stressed beyond the transfer.
Then make the new larger spool the source and wind it back onto the 3DS spool.
Note: the filament wound at the smaller diameter on the spool is now being wound to the inside of the target spool.
That is where I was having huge problems with the Hatchbox and eSun filaments.
The eSun people told me not to do re-spooling!

I will eventually do it, i love all kind of gadgets haha

Are the cubepro carts made of cardware as the Cubex? pretty lame movement on 3DS imho

Hi Tommy As you can see internal spool different but guess winder works the same in principal.

I was concerned re the spool winder clamp wouldn't fit this smooth cubePro spool in order to wind on the replacement filament

When finished next print I will look to do the hack on my machine.

Firmware CubePro 2 .00 so assume this will work as well on this as the Cube 3?

Any suggestions much appreciated.221522132214

Hey @chaman

I did print all the pieces but Im still wondering how to sort the tubes togheter....

I mean, i do have the main structure setup, but the round tube does not fit anywhere inside any of the holes in it ??? :???

EDIT: Nevermind, just realized I need to print some pieces twice lol


06-28-2017, 05:36 PM
hey there
If you still have any problems ,, let me know

06-28-2017, 07:04 PM
All cool! The only issue is somehow the rounded+cubic spool holder piece is too tight on the holes, but I sanded it a bit and it's ok now ;)

06-28-2017, 10:28 PM
Aaaaand here it is ;)

Ok I respooled a couple spools....

First one became "too lose" and took less filament because of missing tension.

Second one, i did use my finger and sometimes my hand to add either / both some tension or "opposing force" to the easyness of the giver spool to unwind, getting the reciever spool to be more tensioned and it took more filament than the first one, plus at the same time it does not do "weird" things like trying to unwind leaving "spaces" over the air...

So perhaps adding a bearing driven wheel somewhere on the path of the filament guide and between both spools could add some tension to the "system" and get better spools for our printers?

Needless to say, I'm NULL at engineering, and the most desireable thing would be to have a "tilting" filament guide too, to allow filling all the spool gaps as soon as you move your lever ;)

PLUS: Leave enough space on the filament guide to feed it with a bit of PFTE tube to prevent filament "grinding" while sliding PLA vs PLA....

The last "small spool" of Printrbot filament I rewound I first rewound onto a stock PrintRBot spool...
That moves the outside coils to the inside...
And immediately following I rewound it onto the stock spool.
Now the inside coils are still inside.
This wound nice and tight without undue filament stress.

For larger filament coils, I do leave it a relaxed wind. It keeps filament from cracking if it has the potential to do so.

Define "small Printrbot" vs "stock Printrbot" :D

07-07-2017, 05:41 PM
1/4kg spool vs 1/2kg spool

This is both on boats...

@chaman just pm'ed u :)

07-31-2017, 07:41 PM
So this is what happens when you respool old (2013) 3DS filament! LOL I left the spool totally "respooled" on friday, only to find it like this today:







It autodestroyed itself! LOL

Nice programmed obsolescence, 3DS! lol

07-31-2017, 08:02 PM
@bolsoncerrado I sent you a private msg

08-01-2017, 12:46 AM
Yep, that is what happened to my clear filament too. Notice that the "small" ID is on the outside now. And all the breaks are from being on the large diameter now.

That is what WYZ told me to never do.

08-01-2017, 09:05 AM
Thats weird though as smaller diameter was stressing the filament more than the cube3 spools, thats really weird. ANyhow, it was OLD so it was somehow expected.

08-01-2017, 04:35 PM
It was definitely old :)

I've had better luck with "double winds" lately.
Move to an intermediate spool 1st.
