Reduction fan 30x30 to 40x40 for XCR 2 IN 1-V2

Hey there! 🙌

Today, I’ve got a practical model for those looking for a quieter print experience. This reduction part is designed to change 30mm fans to 40mm for the Dual XCR 2 IN 1-V2 extruder. I couldn't stand the noise the original fan was making, so I came up with this solution that not only reduces the noise but also boosts cooling efficiency. 💨

If you’re dealing with the same issue and need a fix, I think you’ll be pleasantly surprised by this model. 😎
