3d printed rearset prototype

[xa-mont]

Hey guys,

Thought i would show off my new rearsets that have been 3D printed by my brother after i designed them up in Solidworks.

I'll be fitting it up when they get to me (hopefully he'll send them tomorrow) and if they work well and are in the position i want i'll get them machined up.

That's cool

oh can i come play with yr toys

I want a bike made from yoghurt that has set and gone off a bit

[fimpBIKES]

jealous of the tech!

a suggestion though, instead of infinitely adjustable if the slot had overlapping cresent moon thingys then its easier to get left and right setup equal. still leaves heaps of adjustments/positions but also means if bolts vibrate a bit loose then it isnt a disaster ;)

yeah thinking about just having a few hex indentations in the rear side so that a nut will hold in there so i can only have like 4 different adjustments. At this stage it has a "rail" in the back where a nut will run, but nothing to stop it at any stage. truth be told i'll probably have it at the top of the adjustment only. really just doing it as an experiment and if i get it milled it'll mainly be for the interest factor of it.

man thas real nate bloke!
Im always in awe of thes CAD and solid whatever 3d modells you guys can make and then machine.
My old mans an engineer, and probably has this same softwares. i should hit him up for it, and get some bespoke parts dun!

[fimpBIKES]

to save some $$$ i'd end the slot in a round, not a hex to match the nut
that said...

if u went the couple-of-holes route u could just do a series of tapped holes
would make the part stronger since it wouldnt have that big cut through it (easier to make too)

is it m10 in middle then 4 m6's on the outside diameter mr xa?

how good are the current batches of cad software! like the fancy background LOL

[xa-mont]

you're probably right fimpo Tapped holes will probably be the go for cost saving... also for rigidity when it's all together. It has 10mm of ally there so i think that should hold an m6 thread just fine. I was just over fancy-ing it cause i could for 3d printing :P

And you're spot on m10 in the middle and m6 on the outer, not sure if the m10 is necessary, but thought the extra security in case something did happen with the m6's wasn't a bad idea.

Solidworks is the fucking bomb! It's so intuitive to use. I just need a few more shortcut keys then it'll be easy as pie.

fimp is right.... get rid of the slots for the nuts and just drill and tap some holes.

The hex ends would be impossible to make with the sharp corners anyway.
You have to have a radi in slots because they are made with a round cutter, and the radi should be bigger than the cutter being used.

If you want it to look like it's been made by someone who knows what they are doing, you should break all sharp edges!!!

0.2mm chamfer on the back edge will do and chamfer all the holes too.

If you are using Solidworks, you can use the FEA to get a handle on whether it's strong enough. If you're using Solidworks standard it is a bit basic, but it does do the job with a bit of faffing around.

Tony u do 3d .....
I'll swap u a copy of this yrs inventer for my work done lol
Give me manual machine ill build u anything
let me loose on a pc I sux more than rod at a pofter bush lol

[wackyrider]

Trav, can you post up the link for downloading Solidworks. Might be worth a try at that too
