I have 2 circles, one with a circumference of 325 and one with 160.2212. I need to figure out how to space an object evenly around both circles, while the spaces between the objects around the circumference of a circle are equal on both circles
if that makes any sense

OR

find s

s n = 160.2212
s u = 325
n and u have to be whole numbers

OR

an object has to be space evenly around a circle with circumference of 325 and another circle with circumference of 160.2212. the distance between the objects when they are placed around both circles must be equal

Im 3d designing tank tracks and I need to figure out how to space the notches on the tread and the bumps on the wheel so they fit together.

For example:
One circle has a diameter of 15 and another 20. I can space it out every 5 because 5 multiplies into 15 and 20 evenly. but what about the other numbers??

pls help...

Hi there!

Since last year, I have greatly improved my STL viewer. If you didn’t know: It’s a very fast viewer for Windows which opens any STL, no matter how large or how odd it may be. It allows you to browse folders full of STLs in no time with the left/right arrow keys:

Did you miss Drag & Drop? Now it’s supported!
Prefer US/Imperial units over meters? Not a problem any more, just check the menu!
Have a very old or very weak computer? The viewer now runs even without a graphics card!
… plus many other improvements.

For all those who await OBJ support: Sorry that I didn’t finish it yet, but as you see, the project is anything but dead. Just be patient!

If you have questions or problems, don’t hesitate to ask me!

I am looking for a model of the Panama canal to 3D print for a school event. Does anyone know where I can find one? Thanks!

I curently own 3 printers. Creality CR10. FlashForge Creator Pro and Dreamer.

I very much like all 3 printers. And they do the job intend them to do. Strictly PLA on the CR10 and mostly ABS on the FlashForge machines. Niether of these do well or are even capable of (without exstensive upgrades) to move into the more compliacted prints and material I would like to use.

The CR10 works very well with PLA. But noe much else
The FlashForge machines work well with ABS. They are dual extrusion, but that dosnt work well at all. It does OK, with PLA, but not as good as the CR10.

I need (not want) 1 major thing in my new printer. To be ale to print with Ultem. A secondary want (not need) would be quality dual extrusion for soluable filament.

Anyone know of a printer that will work well with Ultem out the box and may possibly have a dual extrusion?
