**E nder 3 and E nder 3 Pro Fan Silencer Shrouds for PSU**
These are fan silencer shrouds for the E nder 3 and E nder 3 Pro power supply fans. *In the pictures, the E nder 3 shrouds are yellow and the E nder 3 Pro shrouds are purple*. They attach using the original screws that mount the fan to the inside of the power supply case. There are embossed and debossed versions with the E nder logo and with just the E nder dragon. There are versions for the E nder 3 and for the E nder 3 Pro with the Meanwell PSU.
The distance between the screw holes is 69.65 mm for all versions of the model. This seems to be a perfect fit for the E nder 3 PSU, but you should **scale the model up to 101.5% in the X and Y directions for the E nder 3 Pro PSU**.

**IMPORTANT: Never have both screws removed at the same time or the fan will drop into the power supply case.**
1) Remove **one** screw and attach the shroud with it. You may have to drill the holes to be a bit larger, so make sure the screw fits through both holes before attaching the shroud. You probably can do this by hand by just twisting a 3/16" drill bit between your fingers.
2) Pivot the shroud out of the way and remove the second screw.
3) Pivot the shroud in place and secure it with the second screw.

Update 2019-07-08
Added V2 versions which are 1.5 mm shorter to accommodate newer versions of the PSU which have shorter screws. I left the original versions but there should be no reason to use them,…
