This is a modified version of CloakedWayne's Monolith Bed Fans mod. I split the original design into two single fan pieces, so I could use it with my chamber filter.
The A and B parts are different. Don't just mirror one in the slicer.
BOM for two fans
5015 radial fans x2
M3x20 SHCS x4
M3x5x4mm heatset inserts x4
M5x10 BHCS x2
M5 roll in T-nut x2
