I need to 'drill' a small hole in the attached model.

I tried importing it into Sketchup, but its got so much geometry, its impossible. I wondered what other tools I might use and then I consider that Modifiers in Slicer itself might help

I drew a cylinder in the middle of the pellet, and then played around with Infill and Perimeters.. But I can't get the results I want....

I even trued in SuperSlicer and that was a bit better.. BUT.. I could never get rid of the top perimeter for some reason, so I ended up with hole with a roof.

I suspect that the sheer size (tiny) of this makes it impossible.. So perhaps I am better of going back to 'CAD' to make the modification.. If so, what apps are good for this kind of thing?

Thats first class.. Played with MeshMixer a few times and never did anything meaningful with it.. But thats exactly what I want to achieve so will play a bit more.

I have installed a few apps that support STL editing and the files I am trying to edit open in a matter of seconds and look perfect.. Where as in Sketchup they take upwards of an hour and are full of holes.. I want to explore whether there are any better ways to open the files in Sketchup so I can edit them using a tool I am farily familiar with. Or whether there is a way ot convert them to a more "friendly" format.

But using MeshMixer looks like I can DO exactly what I want.. And if I can do this, I am sure there are other functions that I have overlooked too..

 

So cheers for the tip

jon

Using the Part workbench in Freecad, it's possible to 'drill' a hole in any solid piece by creating and positioning a cylinder and then doing a 'cut' operation between them.

I use Fusion 360 for most of my work. 

This would be fairly easy task.

I have no doubt.. If I had my time again I would learn Fusion... But I backed the wrong horse and learned Sketchup and have regretted it since.

For what I use it for, SU is fine.. But I think Fusion would have been a better choice.. I have tried to migrate over, but every time I want to do something, I keep going back to SU as I am familiar with it.
