- The Masterspool is a new concept form Richard Horne that aims to reduce the shipping weight and waste from traditional disposable heavy plastic spools.
By printing or buying a standard sized masterspool you only need to purchase a refill, reducing the shipping weight to just above the mass of the filament. You can also drastically reduce the waste of the spools because they are fully reusable.
I think its a great idea and things are heading in the right direction but I have some thought that I wanted to share.
In this video I take a look at the masterspool v3 and give my thoughts and opinions as well as sharing some ideas for future developments. Testing begins.
This video was based on the V3 masterspool, a version 4 has also been released.

The nice thing about it is that the community can share ideas and get a good solution. 1st steps are done and most important is the definition of the dimensions of the refill and zip tie locations. If companies can agree to that the look and features of the spool can improve over time. Even having own designs aren't a problem as long these following the basic definitions.
I still don't understand how this is an improvement over cardboard, like Proto Pasta uses. Those weigh far less, are even easier to recycle, and don't require the user to print a spool (something they may struggle with on a smaller printer).
6:20 and what does that induce in the print ??
I don't think a snap together spool would work too well, the snapping mechanism would fatigue relatively quickly and render the spool unusable. Kind of defeats the idea of a a reusable spool if you need to reprint one regularly. Maybe a space for a locking pin to stop the threads coming undone, would also give it a fixed alignment point.
Another idea is possibly having the hub/thread independent of the side plates, so you can thread the hub together and the plates have a key slot that located them on the hub. That'll also keep alignment consistent. A push release type ratchet could also be integrated into the the parts that thread together, so it stops them from unthreading when you don't want them to.
i friend of mine designed a master spool with bolts. its not up to date yet but it works and checks two of your points ^^
The filament falling off the spool was a complete nightmare for me. In the end I changed my printer to use a reverse bowden and that "cured" the problem instantly. Masterspool is an awesome idea but it is quite flawed.
I still think filament manufacturers should also sell injection moulded refillable empty spools (or filament with refillable spools) because it takes very long time to print and they will not last as long considering they are 3d printed and will be reused over and over again! Am I right?
Why not have the Filament seller offer spools with either the filament on an injection molded "master spool" together... or just the filament alone. Then when you find you have enough master spools you can order just the filament in the future. If people love the savings from having master spools then people will likely order filament from the first filament provider that ponies up the money for the injection molds... so that filament company would get people biasing there purchases towards their company... at least until the have their fill of master spools... no pun intended. I personally have a large laser cutter so I can cut spools sides and only 3dprint the hub... which is what a filament company could also do... injection mold just the hub and laser cut the spool walls and throw in a bag of nuts and bolts that the customer can use to assemble their spools.
The Master Spool does not have to be printed. It could be made from a plywood, with a cardboard tube, piece of aluminium sheet, etc. How about making one from an existing injection molded spool. Cut off one side and make a side which can be attached.
Lots of options to printing.

I just found your video about the MasterSpool. I just came in to this topic and my first spool was the "Little MasterSpool"(www.thingiverse.com/thing:2791930). Quite a nightmare. When you have two side by side, they cling into each other and the filament tangles off. Then I found the Twist and Lock MasterSpool (www.thingiverse.com/thing:2823667). This needs a "key" to open, but its fast and secure. I'm just printing another one to test with a "fresh" new filament refill.
