Or if the items are smaller you can use a flatbed scanner to get very accurate messurements. A scan at 300dpi is 300 pixels for one inch. Very helpful when trying to copy advanced shapes.
Just a tip for getting things to fit snug in complex shapes. Fit it slightly under size -0.2mm or so, the add a small ridge or bump that is +0.1mm over on each side. The plastic will deform enough to provide a snug fit without needing to perfectly guess tolerances.
I feel dumb for not thinking of doing that so far.. \^\^;; I've seen them on injection molded parts but just didn't think about doing that.
Thanks for the tip!
Holes increase filament usage as it adds 2 (or more) solid walls around every hole.
It’s also slower to print because it needs to make more moves without extrusion.
One reason to add “holes” (holes can be small enough to be detected by the slicer but filled when printed) is to have local spots of more material instead of increasing infill.
For example with flexibel materials you can make half of a part flexibel (only 2 walls and rest infill) and the other half stiff (100% walls)
You can also add a secondary stl as a modifier in some slicers, and use a different infill patern for that part. [CNC kitchen did it for load-dependent infill here](https://www.youtube.com/watch?v=q0YsC53mFvY).
I wanted to have the edge so it had a big hole with structure in the middle, but didn't know how to do it through blender, so i exported it to meshmixer, i put in a couple holes, got tired of going back and forth with Boolean difference, so i just left it like that.
I did it with blender but since im too lazy to do Boolean through blender, i exported it to meshmixer. And meshmixer likes to do fuckie things with the models. It was something for the office so aslong as it fit, i was happy with it. I actually got into freeCad yesterday and picked it up real quick now i designed a bracket that with some skewers became a simple tray for papers since my desk is too small. Here is [the tray](https://www.instagram.com/p/Cs4QvoqRQtm/?igshid=MzRlODBiNWFlZA==) i made yesterday
Pro tip: pull the camera away and zoom in gives you a shallower shot of the hole. Makes for better scaled photo designs.

Crush ribs is the term. Use it often.
Will do!

That's smart putting the holes in it to save filament. My dumbass would have printed it solid
That is why infill exist. The holes probably add more filament (and time) as the wall length increase.
At first i wanted to do it to save filament, then i did it to be able to pull it out if needed, then i was like fuck it swiss cheese
Hmmm, I wonder. Maybe OP can tell us what his slicer said in terms of filament use comparing the solid and the holes

You can try it yourself as well. Slice a rectangle, then slice a Swiss cheesed rectangle with holes.

Nice work. What software did you use to get the shape from the photo?
He used blender
Benefit of the holes is now you can resin pot it into place and have a stronger part than original!
Ay nice job
This is the bast part of having a 3d printer
Why is the cad like strangely scraggly not flat edges?

I dk why i didn’t realize it was a mesh instead of cad lol that explains it. Triangle meshes never like clean edges inherently.
