R2-D2 Dome Mechanism Part 2 by Matt Zwarts Periscope

This is part 2 of the dome mechanism the Periscope Lifter.

Refer to Part 1 and the attached PDF document for parts and assembly details.

NOTE: 24/8/2019 - Updated the main periscope body with back boss and hole details.

Credit to https://www.thingiverse.com/moving_to for the original periscope design :)

When printing weight reduction is something to keep an eye on for the lifts to work easily, so infill on the prints of 15% should be fine with 2 walls.

Note: The assembled periscope lift and periscope body is for reference only, not to be printed.

*Update 25/7/19: Bearing should have been 37OD x 25ID x 7mm wide, PDF corrected and attached, can be sourced here:
