Simple and big filament spool

thingiverse

I was searching for a filament spool that could hold 0.750KG, but all I found were ones that used too much plastic, so I decided to create my own. With ABS, I chose to use rafting on the arms but not in the center piece. The diameter of the holes is 3mm, making it compatible with 2.5mm screws. In the photo, you can see the spool carrying 0.750KG, and I believe it has the potential to hold up to 1KG.
