Dikale Spool Clip

I bought a spool of Dikale PLA from amazon (it was under $20), but the first time I tried to use it, the spool actually came apart (it was two injection molded pieces that fit together). I eventually re-spooled the filament onto another spool, but wanted to be able to use this spool for samples and other filaments I get. However, I didn't want it to come apart so I designed a clip with my son to practice design. This includes a "wing" to help it rotate on the spool holder yet still print flat.

This can be printed flat on the bed, but the "grain" of the print is not very structurally strong. It does work and keeps the spool together. 2 is likely enough, but 3 would be best for a balance and security standpoint.
