Eryone brand cardboard reel adapters

A little project to practice. Since cardboard spools can sometimes (not always, although in terms of build quality, they are better now) cause issues, like slipping during color changes or deforming, some people use black plastic tape on the edges or adapters. Now, I've also joined in by designing and 3D printing custom adapters. These are for Eryone brand spools, and in this case, I'm using PLA HS, which I must say performed well once the filament was calibrated. When creating these adapters, I wanted to add a personal touch. I added a cylinder in the center that can hold bags or silica gel beads. To stylize the exterior, I added some patterns, such as a mandala design, a hexagonal pattern, and a simple single-color one. The adapters fit together on their own, but you can also add a silica gel container, which has only 4 threaded brass inserts M3xH4xD4.2, all secured with 4 DIN_7380 M3x10 screws. Nothing too complicated. I plan to create more custom adapters for other brands to enhance the appearance of even simple cardboard spools. I'm also including a link where you can find the material (step,stl) along with filament profiles and settings. Thank you, and happy working.
