These are some more 834b bits , rear trailing arms , i wanted to make some slightly longer ones for my runner , the black one is just a 1/1 test print with no detail , one of the white ones is a copy of the original but slightly strengthened in the cross brace ribs and the one with DADIO on it is 5 mm longer and constructed differently , I'm printing the long one now in what i hope will be a fairly finished design , the 1/1 copy needs a couple of revisions before i share that either but the pictures show where I'm going .

That's some really nice work. Looks great!

Following your advice i fitted the longer trailing arm to the rear of my runner 834b as a tester printed in draft , very nice fit , only revised one thing and that's to incorporate the washer that's fitted at the front pivot into the design of the arm , this will widen the arm at the pivot and hopefully reduce play at the joint ,i increased it from 10 mm to 12 mm wide so a 20% increase , I have another printing now with this addition and I'll give it a gentle run , I have some PET-G coming so as a final part I'll try it in that material , hopefully the dimensions won't change too much .

I have to say, Dadio, for someone who was completely new to 3D modeling and printing just a few days ago, you appear to be picking this up rather quickly. Those parts shown above are VERY nice!!

I'm more than a little jealous.

I have a lath and mill so I'm used to thinking I 3d and also drawing up designs , I'm also dyslexic and I think that help in these situations .once you get a handle on the software its not that hard just a big initial hill to climb .

Lucky for me, my business makes WAAAAAY under 100k a year so it’s a free license for at least a year. Titan has said that they mean it is year to year, I guess we will know in time for sure but with his relationship with them, I suspect it will remain this way.

Not too sure if I'll make $100.000 this year , maybe next year ?

I've made a start on designing a copy of the original Yokomo YZ-834b top deck/chain guide , this has been a part ive wanted for yeasrs now but they rarely come up for sale and when they do its for a price i could afford but not justify , its been tricky as I've never seen one in the flesh , I've been working off loads of photo's and my own car that lacks this piece to get or guess the dimensions , I've got as far as a working prototype but it needs numerous revisions to get it closer to the original part , I should be able to do the design changes later and print it in draft then I'll post some pictures .

Here we go with the YZ-834b top deck time line , from the first on the left , first is just a flat piece to check the screw alignment , next is still very flat but has the servo saver mount added and a raised edge but i cocked up the dimensions , third is basically what i wanted with the previous version after a few corrections , the fourth is more fully formed with depth but the chain guide was all wrong , the fifth is much better shape but still with hard angles everywhere and a usable design , all just draft quick prints.



Lastly the fifth version installed .

I have a more fully finished version printing now but it wont be done for 3.75 hours

.

The under sides are quite rough on the two more fully formed versions but they were quick draft prints , I'm hoping that a higher res print with denser support will be better , trying to make a copy of the original makes it hard to avoid supports , I could have minimised them by printing it on its side but then the supported edges would have been partially visible so its a no win situation .
