Step 3: glue the servos in the ribs
Attach a servo arm that is just linear to each servo.
Once the plexiglass ribs are cut, embed the servos in each rib. Sand down the plexiglass if you are having trouble fitting the servo in. Make sure that the servo arm can spin freely. If not, readjust the fitting of the servo inside the plexiglass so that it can. Use epoxy to hold them in place.
