How do they work?

Elefilament Refills fit on to the Masterspool.  Just unscrew the 2 halves, insert the 3D printing refill and tighten it up. Line up the cable ties with the slots in the Masterspool.  Undo (DO NOT CUT) the re-usable cable ties and retain in the resealable bag that came with your filament.  Also retain the desiccant gel (which absorbs moisture).

Use the reel as normal.  When you want to change colour, simply replace the colour on to the spool.  To do this, re-tie the cable ties, unscrew the 2 halves and lift the filament off the spool.  Put it back into your bag along with the absorbent gel.  Re-seal the bag and it should keep fresh for the next time.


How do I get my masterspool

At the moment you can download and print your own at thingiverse - or from Myminifactory .  Printing your own spool means you can use up all the odds and ends of material you have since you won't really mind what colour.  The more multi-coloured the better, we say!

Thanks to Richard at Rep Rap for his design - a true hero of the modern age.

Why should I use a masterspool?

The main advantages are cost and reduced waste.  The cost of the reel and a packaging box cost approximately £1.50 - £2, so we can remove this element during manufacture. 

You are also being kinder to the environment by reducing waste.  You will no longer have a postage box or empty spool to deal with (Note, we sometimes still post out using a box).

You will have an extra item - 3 cable ties.  These are re-useable so keep them when your spool is finished and see what else you can keep tidy with them.

We recommend you only use a similar design to the original one.  We have tried many variations available on Thingiverse with poor results.
