Re: 1/10 Caterpillar D8T Build (3D Printed)
I found some 10mm motors with planetary gearboxes that I will be using to extend the stabilizers on my Manitou 2150, I think they are 300rpm. (There are listings similar to the gearboxes I got on Ebay now, just look for 10mm gearbox.) Using an M3 threaded rod as the screw they would move at about 2.5mm/second. The stabilizers have about a 70-80mm travel so I figure it'll take about 20-30 seconds to extend/retract the stabilizers. It works in the 3D model anyway - real-life might be another story.
I originally planned on driving the motor with a 10A ESC, but that would use 8 channels just for the stabilizers. I'm currently looking into auto-leveling using an Arduino and a gyro chip. I had planned on the Arduino running the lights anyway so I might as well make it earn it's keep. But that's a whole 'nuther rabbit hole. Last edited by ddmckee54; 02-07-2023 at 01:09 PM. |

Re: 1/10 Caterpillar D8T Build (3D Printed)
That is beautiful... You have got some great CAD skills

Re: 1/10 Caterpillar D8T Build (3D Printed)
Thanks, took me a while to figure out the shape of the curved sides and i settled with a section of a sphere chopped off a certain distance from the center. This thing is huge and impossible to fit in my 1st gen ender 3 so i had to print in sections... 1 of the 3 sections took 20 hrs to print... 3d printing is truly a hit or miss thing lol...

Re: 1/10 Caterpillar D8T Build (3D Printed)
Build update for today... almost done with the blade, just waiting for blade swing cylinder to finish printing so i can fix the blade and it doesnt swing from side to side...
Here is my CAD model/rendering... and the printed/assembled parts... Last edited by Orange RC Works; 02-18-2023 at 05:23 PM. |

Re: 1/10 Caterpillar D8T Build (3D Printed)
Impressive work. I'm looking forward to seeing future updates
Did you add any weight to the blade? -Shawn- |

Anyway, another update with the installation of the headlight mount and the blade swing cylinder, (unpowered).. |

Re: 1/10 Caterpillar D8T Build (3D Printed)
I can't even begin to wrap my head around the work you must have put into this to achieve that much detail....
I couldn't do it.... |

Re: 1/10 Caterpillar D8T Build (3D Printed)
Thanks, i do like to challenge myself a little bit and it gives me so much satisfaction when i get to figure out a shape in autocad 3d considering that i have to manipulate the WCS to be able to model something working only with basic shapes like cylinder, box, torus, sphere, cone, etc.

Re: 1/10 Caterpillar D8T Build (3D Printed)
That's really an amazing looking build!
It will be interesting when you're done to estimate how many hours you think you've probably got into the cad modelling, vs the parts prep and building Can't wait to see this ready to bulldoze stuff.

Re: 1/10 Caterpillar D8T Build (3D Printed)
Thanks, this would probably end up like a demo build, not sure of the power train being able to push dirt but when i tested it, it can pretty much climb a 30 degree incline but lets see... i can say 3d modeling really takes more time than printing and assembling but im excited to see how it would look when finished and painted.... ill keep you guys posted...cheers.

WooHoo... all the engineering worked...this is going to be killer when you get done...

Re: 1/10 Caterpillar D8T Build (3D Printed)
Quite amazing what can be accomplished with 3D printing in modern times, looks fantastic! Have you kept a separate tally of hrs in design & print?

Re: 1/10 Caterpillar D8T Build (3D Printed)
thanks... i need to do another test video to show movement of the blade and ripper...

Re: 1/10 Caterpillar D8T Build (3D Printed)
thanks, just a rough estimate would be around 220 hrs for design and maybe half of that for the prints... i have used 4 spools more or less since i started this build.
