Infinity Modular Filament Storage – Stack & Expand

Why? After starting with 3D printing, I ran into a common issue: what to do with all the filament rolls and filament boxes? I like the way they look, but having them disorganized or in cardboard boxes did not look that good and made proper use of space around the printer. So I considered looking into a way to store them properly. I started from my main requirements: stackable, both vertical and horizontal, to make proper use of available space, easy to connect and disconnect (for ease of reconfiguration) and easy to print. Project: Print time is around 5 hours, with a modifier added for the vertical arms in order to increase infill for strength, without requiring to much infill for the base, where the weight is distributed on a large surface. Material use is 125g, so with a 1kg roll you can print 8 pieces, which can be stacked 1x8, 2x4 or any combination you need and makes the best use of available space. Printing: Materials: I used both PLA and PETG for testing. Don't think PETG is re
