manta ray automaton manual/motor

Update 2026 Feb 06: N20 Worm Gear Motor to TT adaptor uploaded ( by request)

but since that's a different model, I upload it as a different model, lol

Update 2026 Jan 04: adjust the manual handle a bit bigger for easier turning ( by request)

and some little adjustment no one will ever notice

most stressful model I ever designed 

more then 400 components created and around 2 weeks of testing and fails

was it fun? maybe….but not sure I'll ever do it again

I'm not a story teller 

and in fact…..I don't really talk much in real life 

I'm just a chef….

so…I'll let the model speak for it self

-----

it can be use as manual turning or by a TT motor

I printed with bambu metal PLA, looks cool but kinda dark at the base, 

I'll try bambu copper brown once I got the chance to buy it ( not available for a while )

do not use Silk filament for those support arms, they aren't strong enough for it

make sure you clean up all edges of this part, it will makes lots of noise if you don't ,lol

make sure the top is on this side, I did make a mark on it ( but I can't really see it anyway…)

this one should be tight, use glue if needed

there are marks, one left one right :P

this one should be tight too, but somehow everytime i use PLA metal it become loose

all other color doesn't had any issues 

use glue if needed

assemble this two part 

make sure left side and right side are symmetry before put on the gears

install the tt motor if you have one

and assemble top part to the motor box

this one is really really tight, it needs to be tight

cover those hole if you didn't install motor

install those two gear if you have motor installed

thats all, hope you enjoy it :)

let me know how you like it
