Spool Holder (no hardware required)

After purchasing new filaments, I urgently needed a desiccant box to store them, so I needed to print some storage racks. However, I downloaded many similar models online and encountered many problems during printing.

1. Printing often failed, and the bottom layer suddenly started to fly around, wasting a lot of my precious time, materials, and money.

2. The printed size and quality were not satisfactory.

3. The bearings would run around in the middle. As the structure at the bottom of the box, I hope to put the plate in place once without having to manually adjust the rollers, because I can't see it.

4. I hope my filaments can be as close to the bottom as possible without taking up too much space in the box.

Therefore, I decided to create a new model myself.

First, its specifications must be small enough and absolutely cannot fail to print, because my filaments and time are very expensive, so I added a large bottom area to it.

Second, its bearings should not run around, so I limited them to both ends. Finally, I added new modular notches to both ends so that when my box arrives, I can continue printing its frame according to the size.

I believe this model is suitable for friends who, like me, need a simple, compact, small-sized model that doesn't waste filaments and is extremely stable. After my box arrives, I will post a complete desiccant box photo for everyone's reference.

If you have better suggestions, please feel free to modify my model. Thank you
