I decided to install a roof, for winter, on my Gazebo. This will surely allow me to use it also during the frozen period.
To do this I decided to use a light material like polycarbonate.
Visiting the local forniture shop I found some sheets of this material measuring 200X98 cm. With a Gazebo 4X3 mt I bought 6 sheets of polycarbonate.
To install it I draw some hooks using sketchUp.
This is a special hook I built to install such similar sheet of PolyCarbonate. It is very easy but must be printed using ABS because, if you leave it installed, high temperature could damage the PLA structure during summer.
In the following pictures you will see the gazebo completed in Jan 2018 with a detail of all the hooks I built and installed.
To fix it better to the structure I used some silicon to protect screws from the water but also some resin to reinforce all hooks and the connection between hooks and the structure.
Currently it resist to very strong wind so the result at the moment is perfect. We will see this summer if some PLA I used (reinforced with resin) will resist to the sun. In case I will build new components directly using ABS.
