I designed these boxes to be able to recycle any spool into a nice container.
Like many people with 3D printers, I don’t throw away any of my used spools after they run out of filament. For me, It seemed like it would be a waste to just throw them away so I decided to find a way that I could have a usable container made out of any spool.
For this I turned to Fusion360 and designed a parametric shell that covers the open face of the spool and allows the spool to be turned into a usable container. I made it an octagon to allow for better printing orientations. I designed this to be fully adjustable, use no extra hardware, and not require ANY SUPPORTS! It features a satisfyingly clicky latch and filament hinges.
Here is a short video I made on how to adjust the parameters.
NOTES ON PARAMETER ADJUSTMENT:
- In the file the parameters are labeled
- SPOOLDI: the Spool’s Outer Diameter
- Spool_OW: the spools outer width
- Spool_Width: the width between the two edges of the spool
- LIPTHICKNESS: the thickness you want the lip surrounding the edge to be - Add a little tolerance to all of the measurements to make sure it will fit. I use tolerances that total to around .25mm
- Go a little less with Spool_Width
- Go a little more with Spool_OW and SPOOLDI - LIPTHICKNESS is optional.
Here is a guide picture

Enjoy!
