You can add more male/female joiners to make the rack wider and hold more spools. But, I have not tested how this would affect the strength. If you do this, please comment with your experience. Thank you.
Slot the two corresponding havles of each side brace together. They go together easily.
Screw the pipe sections together. One is male only. One is female only. One is male and female.
Thread the male and female piples onto the male/female joiner pipe. (this can be omitted if you want a shorter rack).
If you want a shorter rack simply just put together the male and female pipe sections.
Slot the ends of the pipes onto the circular extrusions on the side brackets.
Put the pipes on the brackets all the way flush with the sides. Slight force might be needed but do not overdo it
Put your filament spools on the rack and enjoy!
NOTE: Another version will be released that is stackable to hold double the amount of spools. Please follow me for more releases. Also, a release is coming so everything can be printed on P1, X1 and A1 (regular) at the same time. This version the side brackets are one piece; no need to slot them together.
