Drone .stl Files -- Custom Drone Shell #4

Open cmurray3 opened 3 years ago

cmurray3 commented 3 years ago

All,

Here's the article describing the open source design files for the 3DRobitics drone:

The .stl files are attached. 3drobotics-iris.zip

It seems that Raspberry Pi CAD files can be found here:

We use this LiPo battery to power the RPi:

This little device allows us to charge the LiPo and connect the LiPo to the RPi:

For anyone wanting to use Inventor to view and edit the drone shell, I've converted the .stl files and assembled them together in Assembly.iam and Presentation.ipn to show how everything fits together:

When downloading the zip and rebuilding the assembly it Inventor gets mad that there is no ipt file named "iris-Iris-Arm" to solve this just take the .stl and save as an .ipt file. @Danealor you may want to repackage your zip with the "iris-Iris-Arm.ipt" file. Thanks for putting it together!

Danealor commented 3 years ago

Ah yes, thank you. For some reason the iris-Iris-Arm folder was misplaced. That same link should be updated with the fixed zip.

@Danealor would you mind Rebuilding the Assembly with the Scaled Parts Below?

What did you do in order to scale the parts? Are they in their true size now?

It would seem that I'd have to remake the entire assembly basically from scratch with the new scaled parts (replacement fails to correlate the features correctly).

jhulburt commented 3 years ago

The easiest way to rescale them is to make sure your default unit is mm and then reimport your STL files into Inventor Part files. Since STL are unitless until formatted by Inventor there is no way to edit this formatting once complete from what I could tell. I believe they are their true sice now (25.4 x smaller) but I will confirm on thursday.

Alternatively you could use the Derive tool under the 3D-model toolbar but this does not play well with mesh models in my experience and it only wokrs with inventor file types.

Danealor commented 3 years ago

I remade the assembly using the scaled parts. It's easier the second time around. Here you go!

Awesome! Thank you so much!
