Do you want to hold a total of 4 spools above your printer? Do you also hate one of those spools enough to dump like 300g of plastic into a single holder because one broke one time? Do you also have about 8 hours to spend on your printer going in circles?
If you answered yes to any of these then boy do I have the STL for you.
This bad boy is two of the single holders Frankensteined together in Tinkercad like some sort of horror beyond the 3D print gods wildest nightmares.
The plus side to this absolute wasteful use of PLA and affront to both turtles and the EPA is a filament holder that can hold two 1KG spools on each side without so much of a flex, call me Little Ceasar 'cause this allows you to have hot ‘n ready filament for any mid print swaps or reloads, and as a bonus in an emergency situation it’s heavy enough to use as a blunt object for hand to hand combat.
Printing it is pretty straight forward, just requires time. Using Elegoos custom version of Cura I did the “Fine Strength” preset but made the infill 100%, printed with defaults for tree supports, and bumped the speed to 350mm/s, even with that the print took about 8 hours.
Could I have tried to optimize infill patterns and percentages to get equal strength but for less filament and time? Probably but I'm lazy and didn't want another holder to break mid print dumping a spool of filament onto my bed. Feel free to remix though, I enjoy feeding off of others creativity.
The author remixed this model.
Combined two together and made the ring parts a bit thicket had I had issues with them breaking before. Also made the entire thing solid after an issue where one broke mid print.
