Facom 779.PC lamp button replacement

Printing instructions

Printed without support, biggest side down with ironing for the best finish on the visible side.

Then turn the lamp over 

Separate the two halves

Carefully lift the PCB and the charging port to make room :

Insert the printed part in the hole, the missing corner nmatching the L shape on the top right of the lamp
