Abyss3 / Abyss4 - 3D printed quadcopter frame by L3M4R

Last crawled date: 3 years, 3 months ago

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
support for stack 16x16, 20x20 and 25x25 mm
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
20x M2 8mm screws for motors and stack
6x M3 8mm screws for standoffs and canopy
2x 20mm aluminum standoffs (or printed - STL included)
use 20 mm aluminum spacers for maximum frame stiffness ...
... or printed standoffs with different internal thread-hole diameter (2.6-3.2mm
)
best for 2s-3s 400-550mAh battery
frame weight (depends on print parameteres): 3 inch 25g, 4 inch 40g
total weight (without battery) 85-90g
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.
While choosing standoffs (there are 4 variants) use the one that gives you best screw handling - printers usually doesn't print small holes correctly because of not perfect calibration and filament shrinkage. Use the screwdriver gently and slowly while making a thread and give it a while to get cold before checking how it keeps the screw inside. PET-G standoff with designed 3.0mm internal hole may in fact has 2.4mm making inserting the screw impossible. So use the one that will work for you and your material.
