This is my modular Tubular Whoop v8 design. I have been working on this 85mm motor to motor 40mm prop ductless whoop design for a bit now and would love some input. Changing the press-fit, carbon arms can adjust motor to motor size and I have designed brushed motor (6mm & 7mm) mounts as well. The battery slides in above the AIO whop board, which insures better handling.

Print materials: I DON'T RECOMMEND USING PLA - PARTS WILL WARP IF UNDER STRESS/STRAIN. I understand it is easy to print with but PLA's glass transition temp overlaps with temperatures found in a hot car during the spring and summer, regardless of if it is in the sun light.
-Some PETG formulas have the same issue as PLA.
-ABS is recommended
-Nylon is BEST if your print settings are solid.

These are small parts - drop your speed settings (mm/s) to near single digits for best results.
-Deposition rates are in terms of velocity not volumetric rates so for best results your deposition speed should be calculated based on the surface area of your smallest cross-section in your part.

Things you will need:

Carbon Tube Arms: 2mm

• Outside Diameter (OD) (0.0787 inch ~ 0.08 inch works)
• Cut to 32mm for a 85mm motor to motor size (fits 40mm props). I recomemd a Dremel tool with a diamond coated cutting wheel - please wear a mask.

Carbon Tube Cross-Beams:

• 1.5mm Outside Diameter OD (0.059 inch ~ 0.60 inch works)
• Cut to 41mm for a 85mm motor to motor size (fits 40mm props). I recomemd a Dremel tool with a diamond coated cutting wheel - please wear a mask.

Hardware:
Small self tapping screws are used to mount the side plates to the main body. The same screws that are used to screw your whoop boards down should work.

Camera:
-Caddx EOS2 - direct mounting holes on the side plates for this camera.
-Cam Mount v2 for 14x14 size cameras. Would love input on this - or share what you design.

Brushless Motor Mounts:
-These mounts were designed around the Mobula7 0802 motors. - Any motor with a 3 hole mounting pattern on a 6.6mm diameter (center to center).
-Mounting screws - 4, 5, or 6mm M1.4x0.3 (4mm are a little short but still work).

Brushed Motor Mounts:
-The 6mm/7mm motor mounts should be printed in TPU.
