Small mod of the wonderful periscope model with lift found here: https://www.thingiverse.com/thing:2517220.

Removed the top part as not needed when you attach the periscope to the top pie. Also included a modified top pie to better center the periscope when attaching.

The lenses should be printed with transparent filament so you can put some light inside the periscope.

Take a look at my R2D2 blog for more info.

You need the supports just for the periscope. All the other parts can be easily printed without supports.
