Let me start by saying this storage rack is a lifesaver for anyone drowning in filament spools. The heavy-duty iron construction feels like it could survive a tornado, and the adjustable shelves are pure genius.

I loaded mine up with 35 spools (mix of 500g and 1kg) and it didn't even blink. The square tube design keeps everything rock-solid - no wobbling when I grab spools from the bottom shelf. Pro tip: go for the 5-tier if you're serious about printing; you'll fill it faster than you think!

The assembly was shockingly easy - had it together in 20 minutes with the included wrench. Though fair warning: if you try to do the short version (like one reviewer mentioned), you'll have to choose between form and function. I say go full height or don't bother.

My favorite feature? The adjustable width shelves. They perfectly fit my oddball 200g experimental filaments on top while handling chunky 1kg spools below. No more digging through piles of filament boxes!

The only nitpick? Those empty screw holes when using fewer tiers do look a bit unfinished. But honestly, once it's loaded with colorful spools, you won't even notice.

Bottom line: This transformed my chaotic printing corner into something that actually looks professional. Worth every penny for the time it saves searching for filaments alone!
