If you'd like to get your hands on all of the current files, please like my Facebook page (https://www.facebook.com/3dprintair) or visit my website to donate a little money to help me finish the project (www.3dprintair.com). The files for sale come with a dedicated S3D factory file that includes all parts ready to print with their own specialized print settings. This air-frame is currently in development, aiming to assemble all parts together without using glue. With this design, you'll be able to use the 3D printer to duplicate parts and maintain the current air-frame instead of scrapping it because one part is damaged. The frame assembles by sandwiching the wings and motor mount between the top and bottom half of the fuselage. The fuselage is bolted together in 12 places with M3 bolts and nuts. The top and bottom fuselage feature a single extrusion width skin with an internal skeleton of solid bodies, form-fitting wing constraints, motor mounting positions, and servo holders. The skin on the fuselage forms a C shape at its perimeter to provide a strong and durable edge while also securing the wings firmly in place. Servos are aligned to rotate on the exact axis of the control surface and connected via short control wires with two 90-degree bends. Standard 9g servo screws and zip ties secure the servos to their mounts within the fuselage. A hatch in the top fuselage offers quick access to the wing interior for small repairs or battery replacements. The spacious air-frame interior provides dedicated mounting points for FPV systems, accommodating a wide range of battery sizes. The wing and control surface are modeled as solid bodies. Small cuts in their geometry will program most common slicers to create internal geometry (spars and infill) even when printing in vase mode. This creates clean prints with no webs of melted plastic and strong parts with minimal layer imperfections due to the absence of material retraction by the print head. The general specs for the frame are as follows: Wingspan: 480mm Dry Weight: Less than 200 grams Suggested Material: PLA or PETG Recommended Components include: Motor: Maximum of 1308 rpm ESC: Maximum of 20 amps Propeller: 5x3x2 inches maximum Servos: Standard 9g servos Battery: 500mah 2s - 800mah 3s
