BambuLab HEPA Carbon Filter (compatible with Alveo 3D filter)

This is a HEPA filter holder that is mounted on the rear of the BAMBU LAB 3D printer. 
The holder can be equipped with an Alveo3D filter EN-1822 or a HEPA filter H13, and a carbon filter.

These models have a holder for filter and a stand that supports holer safely.  (Alveo filter is 124mm x 124mm x 41mm standard)
The holder can be attached with a neodymium magnet. In addition, for safer mounting, a stand was built underneath to enhance mounting stability.

Motivation 

When the Hepa filter is installed on the rear fan of the BAMBU 3D printer, air resistance is generated without fan. so efficient air exhaust is not achieved. 
To acheive efficient air exhaust, it requires a extra fan that can be forced out. 
Also, the fans, itselt is heavy, so you need a stand to support holder(fan).
