Abyss34 - 3"/4" 3D printed quadcopter frame

thingiverse

Frame inspired by TBS Oblivion and Dave_C_FPV "The Micro Oblivion II" (https://www.thingiverse.com/thing:3792194). The main reason to create frame with support for wider stack mount types and a bit stronger. General notes * 3 and 4 inches propellers * support for stack 16x16, 20x20 and 25x25 mm (if USB socket not on spacer side) * motors 9x9 to 12x12 mounts (1106, 1304, ...) * bigger bay for RX under the stack (not less then 30x15mm) * two versions of bottom plate: 'oblivion style' and simple (classic X) * 3 bladed props for 2-3s, 2 bladed for 4s * 19x19 fpv camera mount + 14x14 mount adapter * 20x M2 8mm screws for motors and stack * 6x M3 8mm screws for standoffs and canopy * 2x 20mm aluminum spacers (or printed - STL included) * best for 2s-3s 400-550mAh battery * frame weight (depends on print parameteres): 3 inch 25g, 4 inch 30-35g * total weight (without battery) 85-90g * designed to be support-less print (print canopy on camera colar) Keep the flight weight below 120g to survive the typical crashes ;-). I have good results using 'Fiberlogy Impact PLA' (it seems better than PETG). No supports needed while print. Make sure FC USB socket will not point to spacer and stack will fit between spacers (14 mm). There is ongoing 4, 5 and 6 inch redesigned version with larger space for stack and 12x12 motor mount and 4.7" DJI Spark motors mount. Version history * 2020-09-30 Initial version, 3 inch bottom plate (oblivion style) * 2020-10-02 Added bottom plate (simple X) * 2020-10-08 Added 4 inch bottom plates (simple) * 2021-02-26 A bit redesigned and stronger Canopy (19x19mm mount), added rubber mounts and 14x14mm camera adapter, fixed 25x25 FC holes (+ missing 0.5mm) * 2021-03-15 Final version for 3-4 inches (fixes) If you appreciate or like my design you can make a small donation - https://paypal.me/L3M4R Thanks
