Im new to 2D printing and been loving it, however y needed a place to store all my filaments as they took a lot of space so i designed this on fusion 360, its literally my third design as i am learning fusion but y really hope this can help someone.

not recomended to print anithing below 20% infill, i used triangles 25% and it worked great, however for the second tube i tried doing it a little faster and lower the infill and one part breaked.

I printed all on an A1 mini and it turned great. 

i`ve tested it with not more than 4kg of weight but if you want more you can just put more infil.

despite this beeing like my third desing and me being really new at this i think it turned out really well and im really happy with the results.
