On doing this for your printer, I strongly recommend you get a metal sleeve to go on the screw and inside of your cylinder. I cant for the life of me remember what its called so I can get you a link, but its basicaly a stainless steel cylinder that I found for the proper length in the hardware section. That adds high quality rigidity, and then use PETG printed larger cylinders to keep em steady. I dont recommend using PLA if you have a heated bed, and even PETG will glass transition if you are using ABS or PC temps.

For simple widgets, sure. When your designs get more complicated, that's just not practical.
This took 20+ prints to get perfect, and would cost around $75 each from Shapeways.
Yeah, but logistically thats a very easy design you have there. a few extrudes here, some counter sinking there, and really its a design someone with no experience could figure out in a weekend if they are smart enough :shock:
On a little lighter side, does it make sense to print this item this way?
The Note in the read.me file says
"Notes:
prints standing on its side so no support needed depending on material on your printer, I use ABS, so I printed with support for the one with places made for furniture tabs to get ite perfekt in size"
To me it makes more sense to print it laying on it's back with the legs up. I did start it that way and it printed strange, You would think that it would lay down the 60x65mm outline then fill it but it didn't it put a rectangle at each end filled them but not in a conventional pattern. Then just` running parallel lines between the 2 end boxes. Wasn't sticking good and I didn't like the way it was going to I cancelled.
Currently printing as per instructions on it's side but I don't see how this is going to happen with no supports.
Rotate 90 degrees obviously...
You know I knew in my mind that it wasn't going to work, no way in he** could that be printed like that without supports, but I just had to try it. ;-) Here's the results
I was watching it so it didn't turn out being a big mess....
External Perimeters was not checked, is now
Top/Bottom infill was rectilinear, changed to concentric
I have Slic3r 1.40.1 rc1 but haven't use it yet, will switch now
Last i checked.. Shapeways is 3d prining.
Ragging on people, not my style.
If your print doesnt come out the way you designed it even after "long" hours of measuring. Its not you, may be the way it was printed or how it was sitting in the file befor the print started.
Measure.
Measure again.
And measure once more.
Seriously, its not that hard. I designed a pan car in highschool in 10 hours. Still have the renderings. Its basic geometry.

The 3D cad work was straightforward. Conceptualizing the design, testing the design, eliminating interference with other components and getting all of the mounting points to align perfectly is where the majority of my time and test prints were spent.

In my experience, cad is pretty easy, measuring things is hard.

When laying the stand on it's back with the legs up it prints really strange. You can see in the time-lapse what I am talking about. https://gramps50.smugmug.com/Duplicator-i3d-Plus/i-P4d2gxL/A Here's what the bottom looks like and it was printing on glass. To me it appears that it didn't press the 1st layer to the glass. It did on the 1st rectangles that were laid down.
I'm pretty sure it's going to be to short for the buggy I printed it for, the buggy won't arrive until tomorrow. Guess I'll design my own and see how it goes.

Did you look at the layer view in Slic3r to see what the first layer looks like? Did it show the gap in the middle?
I am wondering if you got a bad STL file.
Thats the joys of iterative design! Its a fun journey, not a meddlesome task IMO.

Cad is only easy if you know the order of operations that something must be designed in. And measuring is only hard when you don't have that initial reference point.
The layer view shows the strange pattern but I'm don't think it actually showed the gap in the middle.
Here's the link to it https://www.thingiverse.com/thing:1401210 I printed the one without the place for the pads

Agreed, you put it to words far better than I did.

Rule #1 - Fillets are always done last. :lmao:
OMG I couldnt even even begin to remember how many times I farked myself by doing fillets along the way. :evil:
But theres a learning curve like with anything, once you develop your own techniques though it gets easier and then you start challenging yourself. :mrgreen:
Inventor has been fool proof and is the perfect level of dumby pro-ness for me "thumbsup"
That's why I frown on sketch fillets. The can screw so much up and you spend an hour trouble shooting only to find out it's a ****ing fillet! :shock:

Sound advice, but to late. I learned it the hard way.
You are correct about challenging yourself., I have gone from simple spacers to designing and printing a tenth scale flsky gt3c in a few months, with various brackets, mounts and parts along the way. My son asked me for a center console for his wraith last night, I literally sat down designed something in 5 minutes, and had it on the printer.
Fusion 360 has a handy little time line where I can go back and edit each feature that I do. That has alleviated much of my issues, but sometimes it is easier to start from scratch, especially when it is the order of operations that was screwed up.
Now if I could just learn how to place two holes a specific distance apart without zooming in and counting grid marks life would be swell.

I'm not familiar with fusion, but couldn't you use dimensions? Or is that only inventor?

I am sure there are lots of things I could use, but finding them and learning them has been the challenge. Fusion 360 is not intuitive, and has lots of bells and whistles. Almost too many. It does have a great online community with lots of videos and walk throughs.
Is inventor something worth looking into? Just looked it up, it is also an Autodesk application.
