Prusa Bear Hemera Filament sensor mod

Hello,
So I have finally finished testing this and am now happy to release this to you all for free!

I am happy how it has come out and works very well. this is about 2 weeks of constant design and print testing!

The attached files have the M3 screw sizes needed for each part in thier description.

Build the sensor up as to the oem 'prusa' Manuel states, also the filament tube is in the 'cad' also for a cut template.

Build this unit up using Greg's original bearmera manual.
supports are needed for some, the front filament housing and the front fan mount, pictures added for reference, i used a support enforcer for the housing.

it would be appreciated if anyone feels the need to tip me as this has been a long road and a free coffee would be greatly appreciated.

(update 30/54/20)
as requested I have added a M6 Bowden adaptor for the sensor top for MMU

thanks,
James.
