Default Yo-clone-oh Dogfighter YZ-834b

This could have gone in the "i made this " section of the forum and I'll put a link in there as well but i think it will be better appreciated here .
This is a 3D printing project I've been working on to build a replica of the Yokomo YZ-834b Dogfighter , it started as just a way to produce a few spares for my runner and the list if bits i made grew and grew , then it became more of a list of bits i had not made .... it became inevitable at that point that I'd complete the set . Most of it is faithfully reproduced with a few parts either made stronger or redesigned in a way more favorable to 3D printing .


New gears in the original box , diff is printed but not shown as I'm waiting on parts .


Original gears in a newly printed prototype gearbox .



The Chassis is Kydex and also hand made by me , all the other parts you see are 3D printed other than where i show the my gearbox with stock gears and vice versa.
Right now a more finalized version of the gearbox is printing , its only got minor changes to the design of the original in order to make it printable , the design of the gears is unchanged and compatible with an original gearbox .

I've only got an Ender 3, so nothing fancy , I've got a better extruder ,Bltouch and the upgrade board with Trinamic 2208 stepper drivers, its still fairly basic but it does what I want it to .
The gearbox is now virtually complete except the diff , I made some sprockets for the chain today as well as more gears , it takes a bit of trial and error printing gears to get the mesh right , Fusion 360 ( the CAD software) has a gear making add on but you have to get the lash right as well as some other bits to get them to run smooth . The sprockets are not from the Fusion 360 add on , I had to just freehand copy them from originals and that was very hit and miss but on my 4th or 5th attempt I got a good result with both positive engagement and smoothness .
I'm waiting on thrust washers and bearings for the diff then I'll fire up the lath and make the outdrives and front drive parts .
