I recently purchased the Rowenta SO9266 Mini Excel Eco Safe fan heater, and so far I'll love it, but for me it has one big flaw: the rear handle is so uncomfortable, and I even dropped it one time.
So I designed a structural handle, that allows a much easier moving
The project needs a big printer, as the size of the heater is quite big for a 3d printer (I used a sidewinder)
You can secure it with a couple of biadhesive tape pieces to allow it to be moved even upside down as I showed in the pictures
