The following image shows the inner frame with beams, without PVC tubes, pixracerplate and gpsplate.

The inner frame is 3D printed.

The design data is in the Onshape Searchwing-Frame Document. The frame is composed of

• Sidewall-left
• Sidewall-right
• Innerwall
• pixracerplate
• gpsplate

The 3D Print for the walls is done with Ultimaker 3 with “Normal” default print settings plus 2mm wall width. The plates are printed with “Normal” Settings with the Ultimaker 2+. Both use default PLA material. After the print:

• Remove the support brim by hand
• Remove the remaining support brim parts from the walls by filing. The innerwall has to fit into the sidewalls.
• The sidewalls have a 10mm hole and a 4mm hole for the fuselage spar beams. After print the beams do not fit.
• Drill a 10mm and a 4mm hole with the stand drill machine to make the fit. DO NOT USE A HAND DRILL!
• Check that the fuselage beams can be inserted in the sidewall holes.
