Curse you Valcrow..you just keep moving the finish line ...


But then what fun would it be if after you cross the finish line?

What about colored laser pointers for the energy hardpoints on that thing? Good idea? U could make a diorama of an Atlas alphaing sth. BAP for example. Lol.
A diarama... with Lasers you say?? you mean this?

Hi, that's really good work on the atlas... I loved your 'pults, and I plan on making my own. The Sarah's is pretty freaking cool, too- complete with paint job!
As the risk of repeating what others have said - I read the first 5 pages of posts, but there are waaay to many pages ---
---can you share the data for the joints? (Not for the atlas itself, obviously, because IP etcetc.) I'm not sure how to go about making joints myself. I have a printer being delivered, because I had to build my own catapult after I saw yours [INSPIRED].
Otherwise, advice for making joints!
This girl is gonna have a K2, even if she has to buy a printer (done) and make it herself (...could take a while)
Wonderful! welcome to the 3D printing club.
I'm happy to hear my work as piqued some inspiration! As Kiriage mentioned, I have some breakdowns scattered around various threads. This particular one will help.
For joints, you would be better off designing them rather than using what I have. for a few reasons.
-orientation
(each part needs to be orientated to optimize print quality. this affects 'pin holes' especially. If you print a square hole and a square pin they will not fit if your square hole is angled with it's side parallel to the ground because of the resulting overhang of material in the printed hole. If you print the same hole rotated 45 degrees, it will fit.)
-tolerance
(depending on printer accuracy, material shrink, etc.) you will need to test the accuracy of your pins by printing/testing... no way around this... and very good info to learn about the characteristics of your printer.
-friction/limits
Pins usually have 2 problems, how they go in, and how they stay in place... depending on your tolerance test, you should design your pin to have enough give for the pin to go in, and 'lock' into place with a decent amount of friction. Otherwise your model will not stand by itself and just flop around... again. needs testing.
Feel free to model my joint designs and build upon them. I'm constantly revising my own stuff as well. If you look back at the catapult, and even the atlas, the pins were a lot different. They were like little bones. I've since moved away from that in favor of larger diameter pins with tiny surface grades and bumps because I find it works well with my printer.
You'll quickly get a feel for what works and what doesn't and that's far more invaluable than using what I have here. Overengineer stuff. it's fun. And if you get stuck, there's tons of people here that'll help you out!
Which printer did you end up getting?
