We run a commercial 3D printing farm. We have literally thrown away hundreds of spools and we hate it. The weight of the spools increases our freight cost, and they are just a waste of plastic in general, not to mention the environment issues. So we created this reusable filament spool as a resource to filament manufacturers that wish to eliminate the cost of spools to their customers and in their production.
We recently ran across the MasterSpool, by RichRep and while he had a good concept for individual 3D printers, the MasterSpool doesn't work at the larger scale. It uses too much material and has more Guff associated with it than what we want. So we continued on and designed a spool that we wanted to use in our printer farm.
The SlantSpool is just one piece, printed twice. We created a special latching system, so there is no right and left. You can put any two of the SlantSpool halves together. This is great when you have a lot of them because you don't have to worry about printing a right and left, which saves some mental effort, and if you ever break one, all you have to do is grab a half that isn't being used. There is only one spare part you need.
We operate a 3D printing farm that competes with injection molding. We are working with filament suppliers to manufacture these rolls at scale now. In order to make that production affordable at scale we had to reduce the material used. The MasterSpool is too beefy to be manufactured at scale with 3D printing.
So we went ahead and reduced the material needed by half. We made the outer walls thinner and used ribs along the inside of the walls to give it the necessary rigidity. Then we changed the securing mechanism of the Spool to a design that decreased the surface area of the spool so that it prints more quickly and uses less material to create the walls.
The connecting system is actually the true innovation in the SlantSpool. We have made a quarter-turn system that is fast and easy to put together. You just press the two halves together, twist, and it is latched. This is much faster than spinning the halves several times to get them to stick together.
The SlantSpool was designed for the either the frugal Maker or the commercial user. Anyone that would like to have many of these manufactured for their filament refills may contact us at firstname.lastname@example.org or visit us at Slant3D.com
Here are the manufactures that currently produce filament refills for the SlantSpools
-Keene Village Plastics
-Ultimate 3D Printing Store
*The SlantSpool is not yet compatible with MasterSpool refills. We intend to add a variant that is soon.
Dimensions of 1KG SlantSpool to Check Compatibility with your refills
This is the standard spool for use with a 1KG Refill
1KG 6 inch SlantSpool
For those with narrow or small 3D printers. This 1KG Spool is the one to go for.
5 LB SlantSpool
If you move as much plastic as we do, even swapping spools is a pain. So we created a 5LB reusable spool for those large print projects.
One day of production of the SlantSpool. For those that either don't want to or can't print their own.
In our partnership with KVP we have started production of the SlantSpool for those that either can't or simply don't want to print it themselves. The printed spool can be purchased on the KVP website listed above.
