Mirrored M3D Micro Spool Holder

This is a mirrored version of **lindstorm**'s original M3D Spool Holder for 120mm spools. Pictured above is the part printed in "Satellite Silver", with the spool of PLA that printed it mounted to the part. This design is posted for convenience's sake - I mirrored the part in OpenSTL, because I needed it to mount the 250mm spools that I use.
