Bambu Lab Active Activated Carbon Filter Box

I seem to be slightly obsessed with magnets at the minute after building a bentobox v2.https://www.printables.com/model/272525-bentobox-v20-carbon-filter-for-bambu-lab-x1c-enclo I have been inspired by it to build a similar little box for the back of the machine. Using some super glue and the same size magnets, 4x2mm which i bought off amazon….https://www.amazon.co.uk/dp/B0BVDR1BR9?ref=ppx_yo2ov_dt_b_product_details&th=1Nice little recess on the front to grab the box out of the machine. I have sausage fingers and can grip it just fine.Made for Bambu X1 Carbon - Printed in Bambu Lab ASA with all standard RFID settings except increased bed temp from 90c to 110c. Textured PEI with 3DLAC and a brim otherwise this stuff tries to lift off the bed.Can you guess what the grill pattern is?
