This overview of my working 3D printed sequential dog box transmission. I think this turned out great and I'm excited to share this with the world. Thanks.
This is a link to my Github repository. I have the STL files available, but I am still working on creating a bill of materials and creating an instructional video on how to assemble and tune the transmission.

I really appreciate you give exposition and take the time to really teach what's happening here. So many technical 3D printing channels just go "here's the finished product, look at it go" with no explanation.... So thank you!!!

Thank you, the problem with the F1 gearbox is that is much more complicated but this one is a better solution for anyone who want to make it in metal and implement it in real applications, I suggest to you to make an improved design of the sequential transmission and offer it for sale. Thank you so much

Dude! You're on Hackaday! Subbed- this is pretty freaking awesome. I'm a machinist and watchmaker- familiar with dog clutches (see screwcutting clutches added on to lathes for threadcutting ability, like Graham Meek's screwcutting clutch for Myford lathe, and Hardinge lathes came with one). Heard about these in cars as an exotic thing that existed but never saw an easy to understand model of this. Thank you for making your designs public- you could totally sell this as a kit- I'd buy it. Awesome work, this is really impressive!

How cool would this be to set up with a sim racing rig and have it attached to a vibrator under the seat. While the shifter can be wired up to actually changing gears, the motor is controlled by feedback from the games revs. With the gears and motor working together it could make for a pretty choice experience, plus it would make for a cool show piece to show off to ya mates

Well done video, thanks for putting this out there! Sorry if I missed it in the video, but did you mention what filament type you used to make the gears? PLA, PETG, or something else? Any idea how many RPM the motor is going and the output RPMs? In any case, nice job, really fun to see the guts of that thing in action!
@IndeterminateDesign
@IndeterminateDesign 4 жыл бұрын
I used PLA Plus for everything. I think you should be able to use PETG as well, but stiffness is really important. The motor I'm using is a nema 17 stepper rotating around 400-500rpm. I tried a much faster motor and honestly it didn't shift any better and it was a bit of a safety concern.

@greymatterfan 4 жыл бұрын
@@IndeterminateDesign Ok thanks! I made a few smaller gears using PETG so I was just curious. I made a pulley for a v-belt out of PLA though, and I've been surprised how long it's lasted. Thanks for the motor specs, it's nice to know the RPMs.

What happens if the dogs on the sliders coincide exactly with the dogs on the gear (instead of the openings) at the moment of shifting? Would you be unable to shift? Would it wear down the dogs?
@IndeterminateDesign
@IndeterminateDesign 4 жыл бұрын
It doesn't really cause any wear as these are typically a smooth oil coated surface. As long as the input shaft is spinning these slide quickly into place and it would be imperceptible even at a few hundred RPM. But if the engine was turned off yes you will be unable to engage the gear if the dogs and slider were aligned.

I think a 3D printed gearbox in a go cart would be awesome. It does have a reverse, but this design won't take that kind of load. The next project I am working on has a better chance of being able to do something like that. I'm thinking about printing it out in carbon fiber reinforced polycarbonate at some point to see how much power it could handle.

@@miclairmiclair876 I wish I could, unfortunately I'm not setup right now to do these in kit form. You could send the STL files to a 3d printing service, but being a first revision of the design I'd be hesitant as I know some parts may need to be tweaked to the particular tolerances of the 3d printer being used. FDM 3D printing unfortunately isn't a perfectly accurate technology.

Awesome work. I would like to try to 3d print and assemble. Is there a build spec sheet? I've looked in the files I downloaded from Github but I do not see one. I see a readme file but it is an md file. It opens in notepad but looks like html code. Thanks in advance. If I am successful with this I will then tackle your F1 gearbox

I just have the HTML reader file which should show when you go to the page github.com/indeterminatedesign/SequentialDogbox/tree/Release-1. I also recommend downloading the step file for understanding how it goes together and because some parts may need changes depending on your printer’s tolerances.

Definitely, using something like a Teensy you could just read the gear position pot and send a keyboard command to the PC over USB. I'm tempted to try that with my F1 transmission I'm building right now.

If I had to do it over again I wouldn't design all of the assemblies in one file. It can bog down pretty badly recalculating all the complex shapes like fully filleted gears.
