Summary

Just something I quickly hacked together to be able to feed my printer from a second Robox spool which is not in the printer.

I had some ~10mm plastic pipe laying around, so I used that to connect sides of the holder together and also as an axle that goes through the spool.

Version 2 of the middle path has teeth to grap the reel. This way the same setup can be used to spool different filaments on a Robox SmartReel using a drill.

Version 3 has a slot to accommodate for manually winching filament on the spool. Version 4 has a square hole through the whole adapter. A crank arm and related parts are only needed for this.
A round axle and robox adapter is recommended is crank arm will not be used.

I also added a taller version to accommodate for bigger 1kg spools. New spool adapters fit 3DPrima, Colorfabb and Taulman spools. These are not mandatory as the center of these spools is already a round hole (unlike Robox SmartReels which pretty much require an adapter for smooth use). Note that these reels are also wider than the robox reels, so make the holder and axle wide enough if you plan to use different reels.

Instructions

I printed from PLA using ~15-20% infill. 4 top and bottom layers, 3 perimiters. No scaling for any parts except for the crank axle, where I used the scaled down version.

If printing from ABS (or other materials) scale up to keep the original size, so reels will still fit as expected.

Brilliant! You've saved me time doing the same myself!

But, could you, please, add slots(*) in the hole in the middle of the adapter so we can print axle + crank for winding?

(*) in other words - if you subtract a rectangle through the centre of the adapter (where the whole is) that is roughly 1.2-1.5 times wider than diameter and no more than half of diameter tall...

Alternatively if you share original file (and it is done by some free software) I don't mind doing it myself.

Sure, I'll do both. Original files are made with FreeCAD. I'll upload those.

Thanks! I can already see what I'll be printing over weekend! :)

What did you use on those pictures above to connect sides? 10mm pipe? If so - what length?
I've just measured holes and they are around 8.6mm in diameter (printed with ABS @102% (oh, dang - 100%, I forgot to size the sides - middle printed @ 102% and fits quite well).

I'll design and print connectors if you give me the correct length...

I have now printed two of these. The black/yellow with 70mm connectors and the gray one (the taller version) with 80mm connectors. I added photos of both. Preferred width depends on the reels you want to use. 70mm for Robox SmartReels and 80mm is enough for all these big 1 kg reels I have.

I printed mine from PLA, didn't scale. Squashed the pipe in with force. The tall version has 10mm slots for the connectors, so it fit more nicely and then I glued it together.

Thanks! I just sent a distancer to print with 65mm width and read e-mails you saying it is 70mm. Had enough time to stop the print, fix it and now I restarted it.

I am printing in ABS and crank shaft came really badly - so I re-design it with block at the other end as well hoping that it will keep it down on the bed. If it works well I'll send you stl to include with rest of the stuff on this page.
