Description
7.5 Update: Optimized latch structure
12.21 Update: A version with only the adapter ring function, without the speed controller module, has been added at the request of users, see the last two plates
11.17 Update: An optimized version has been created; the fan screw mounting position has added a 1mm thick countersink. The speed controller mounting position now features pre-drilled holes for securing with set screws. M4 outer diameter, M3 inner diameter, and 4mm length set screws are recommended
The first version’s exposed fan was aesthetically unappealing; however, it may suffice if aesthetics are not a primary concern
Compatible with Xiaomi air purifier filter generations 1, 2, and 3, with dimensions of 20cm x 29cm
Available in 12cm and 14cm fan sizes. Printing plates 3/4 is recommended for a simpler structure requiring fewer supports. Printing plates 1/2 requires manually adjusting the latch contour compensation for the split structure
Fastening utilizes M4 outer diameter and M3 inner diameter set screws appropriate for fan thickness
For the PWM speed controller, choose the type with a white or orange button; white ones are readily available for around 15 RMB online. Orange ones are also suitable, although slightly shorter in length and larger in overall size
An inner filter bucket has also been designed; this can be used in conjunction with single-bucket purifiers https://makerworld.com/zh/models/750478#profileId-684089
