Say Goodbye to Empty Spools

The Masterspool has arrived.
Refill your spool as many times as you like. Save the planet.







Mastering the Masterspool 

  1. Download and print your Masterspool. Here’s a file you can use.
  2. When you’re ready to fill the spool, choose from our range of lovely, 750g spool-less filament.
  3. Unscrew the spool, load your filament securing the end strand into the notch in the spool and screw back together. It takes seconds (30 to be precise).
  4. Don’t forget to remove the cable ties!


Why isn’t this cheaper than spooled filament?

Since 1kg of filament with a spool costs £32, 750g of filament with no spool should cost less than this, right?

Not quite.

Neatly winding mass amounts of lovely filament is a more fiddly and time-consuming process when there’s no spool to wind it round.

This means that spool-less filament costs more to manufacture.

So, don’t feel fobbed off by the price. We like to play fair.  

The Masterspool design is considerate of our environment and we’re a big fan.

Oh, did we mention you’ll also save money on shipping?

Order your Masterspool refill today and look forward to less waste, hassle and guilt. 

Please note, this is a 750g net weight spool. This means you'll receive a minimum of 750g of filament, plus minimal packaging (cable ties and vacuum sealed bag). The Masterspool refills do not come packaged inside a box as standard, but if you require a box then add this to your notes at the checkout. Our regular 1KG spools of filament are minimum of 1000g of filament, plus approximately 245g of spool, plus cardboard box. 

Customer Reviews

Based on 3 reviews

First of all I am still getting great quality prints, so these comments about the Masterspool filament are niggles rather than show stoppers. When it arrived it was *not* vacuum packed, as a result a bend test showed it broke more easily than the standard reel mounted fare. The outer end was marked with a piece of masking tape, but I had to search for the inner end. Unlike the Masterspool video on Thingieverse (different supplier) the end was not positioned in the correct place to clip into the Masterspool and had to be trimmed to fit.

I will definitely be buying again. Love the sweets, but not sure that my waist line agrees.

Hi Chris,

Thanks for taking the time to leave this review. and I'm glad to hear you're getting great quality prints.

I may be able to explain why your refill wasn't vacuum sealed, there was a technical issue with this in our factory so we made a decision that it would be much better to place them in the Mylar resealable bags with an active desiccant.

I can confirm that future batches will be vacuum sealed like our other spools.

As for finding the inner end and getting it to clip in place do you have any suggestions on how we can make this an easier process?

We could also mark the inner end with tape, do you feel this would help?

I really appreciate you taking the time to give us this feedback as we can't improve if we don't know the issues :)

All the best,
looks to be good

I am new to 3d printing, and so far the materials and advice I have been given has been very good.
