RHD BMG heat shield
thingiverse
The RHD fan duct works great but I was having catastrophic false thermal runaway errors whenever I ran up my blower to more than about 30%. Tried at least a dozen different PID tunes to no avail. The silicone sock from Slice didnt fit right in the BMG with this duct so I made a little heat shield / draft guard / air dam from a soda can. Works a treat now! Only real hassle with it is that you need to remove the nozzle to install/remove the shield. The attached PDF clan printed full size on A4 or US letter to be used as a guide.
