Here is a simple holder for Sharp sensor . Not printed yet , if you do , feel free to give me your opinion .
There is a channel to pass the thread under the holder.
The holes for attaching the sensor are for M3 screws with nuts 5.5mm.
The holes for attaching the support are for M4 screws with nuts 7mm.
EDIT 07/4/2016 : Height increased by 5mm to allow more space to the connector.
