CinePunk3 R3 - 3D printed cinematic quadcopter frame

CinePunk Release 3 (3 inch)

• symmetrical, modular cinematic quadcopter frame
• dual HD camera support (mounted on front and rear)
• designed for both: flexible (TPU) or stiff (PETG) ducts versions
• removable propeller ring to support TPU duct geometry
• propeller ring can be changed to adjust the gap between propeller tip and duct
• easy to repair/print by modularity, almost no supports needed
• replacable duct top, reduced number of screws to remove top plate
• printed spacers with rotation blockers
• motor arms geometry adapted for better airflow
• USB plug friendly, tunnels from sides to plug USB without angle plug
• use M2 5-8 mm screws (optionaly washers) to assemble

General notes

• this is intentionally 'strong type' frame (for duct frames, not in general :-))
• frame becomes very stiff after assembling, flexible plates are not a problem
• use proper motors, for example emax rs1606 has no power shortages in my case
• use bullnose propellers and very small propeller clearance for best efficiency/flight time
• if you think about people security only there are lighter frames you should try
• included extra plate as template for custom HD camera mounts
• GoProp camera mount (round, screws), put the spacer below mount

TO DO

• HD camera mounts (need help with this)
• extra mounts for foam for ducts
• alternative camera and antenna mounts
• carbon fiber plates

Notes:

Let's start with

• ducts and mounts: 10% infill and 2/4/4 for walls/bottom/top for
• plates: 30-40% infill and 3/3/3 walls/bottom/top
• 100% infill for spacers

0.2 layer height will work, to improve precision it can be 0.12.

FILAMENT

Ducts may be flexible (TPU) or stiff (PETG, NYLON).

RETRACTION

If you have well calibrated printer it is possible to print ducts using single wall (PETG). Make sure your retraction is very good tuned for 1 wall duct prints - it is possible to have very lightweight ducts but to make 1 layer walls (0.4 mm) you have to be sure all filaments goes to walls, not to the air (strings).

CLEARANCE

The propeller has .3mm clearance (margin/gap/distance between end of propeller and inner duct wall), so it is shoulg give you .6 mm on both sides of proppeller. Notice that diffrent materials (PLA, PETG) has different shrinkage side effect, so in fact your print finally becomes a bit smaller (1-3%). So right after mounting motors and propellers use bottom motor bolts to tune the 'axis' to make is well centered (I'm experimenting with sprint washers also) and use sand paper to clean internal duct surface to give propeller needed space.

SPACERS

Print verticaly for good geometry and horizontally (use sand paper to make it perfect) for best stiffness.

Post-Printing

Assemble tips

• M2 4-8 mm screws
• optiomnally use screw washers from the bottom of motors mounts
• use sand paper to gently clean mount surfaces to be able to use screws more comfortable
• make sure propeller ring is very clean, use sand paper to fix it or use alternative propeller rin
• for propeller ring make sure inner surface has no blobs
• before assemble carefully create the threads using hex screw and driver
