3D Printing Thread

Can anyone suggest a free and easy to use tool to modify STL files? I have a simple requirement (see attached) and think I may be able to it myself by modifying an STL on Thingsverse. Any help is appreciated. Cheers.
I can try to help you with any modifications through CAD if you can share the file.

Thanks so much, man! Basically, id like to keep the holes in the same places just the center part cutout.

Just to clarify, i would like the output like the white frame.

STL is at the link below (couldn't attach as it's too large)

I would like the height of the frame to be 10mm please.

Thank you again!

Done! The file is uploaded to Thingiverse: https://www.thingiverse.com/thing:6666099. Let me know if any changes need to be made...
 
What software are you using to modify the STL file? I tried blender which does work good with mesh files but is not suitable for CAD related.

I recreated the model from scratch
in fusion 360 from the 120mm fan specifications. The geometry was pretty simple...
Let me know if you need help with modelling anything...

Hey, new to 3d printing here. Glad to see there already is a community around this.
I've placed the order, but not gotten my printer yet.
Wanted to ask what 3d software people use to model and what do you all suggest I learn?
I know 2d autocad and sketchup.
Thanks.

Hey that great to know. I personally use Fusion, but have shifted to onshape. For slicing I use Prusaslicer. Sketch up is amazing to begin with and you can in fact use it for 3d prints. Seems like you're re you an architect. Also what printer did you get...

Haha my software suite gave it away. I did study to be an architect, but I do custom work with glass and resin now.
What about you?
Great that I can use Sketchup to start. After that you recommend Fusion 360? I heard a lot about Orca slicer.
I got the Neptune 4 max because it was the biggest I could afford. Plan on using it for work to make moulds for casting.
Going a little crazy with the number of 3d printer reviews and "5 things to know before 3d printing" videos on youtube.

I have the "humble" Ender 3. Good you went for the large print module. A warning that if you plan to modify even one part, you'll end up spending more than the cost of the printer in upgrades. Fusion is great, so is Onshape. Why not try both and see. Same for OrcaSlicer.

Nice to see you do casting. You create a sand cast from the 3d printed parts, right? I'm from a MechE background and usually design and print functional parts like brackets, enclosures, etc, so the Ender 3 is perfect. Attached some pics of the printer if you're interested...

Man these tech things always look enticed ng to me and keep on making me buy them on whim. Only thing keeping me at bay is that i don't have time to make myself indulge in these due to very lack of time because of work.
Sometimes i think of starting a YouTube channel for these techs as i love to do these and like to make myself indulge in these but then a YouTube channel is not a sureshot way to earn a living but i also am not able to try on sides too.

Dude, that's so cool. Very interested.
Yea I'll try both those software and see what works more intuitively for me.

I'd like to try sandcasting but not there yet. Figured I'd start with silicone moulds for casting resin. It's a new avenue I'm going into as far as work is concerned. I don't know squat about any of it. My usual work is more along the lines of flat glass panels with designs and such. 3d for me is layering glass but that gets very heavy very fast.
Hey tell me, in our climate, does pla have issues with say things like drawer organisors or wall peg board cups to hold screws or small tools?

The kind of work I do, incase you are interested in seeing: Google photos album
Basically the opposite of you, decorative but not much functionality

Yeah, but the larger publishers always get ahead due to their company-size production and teams. The blogging space is even worse after Sep 2023 due to Google. I have some much to write on my own site but the time is just not there.

That's genuinely amazing. The scale is mindblowing. Do you use some kind of solder to join the glass pieces?

PLA is not that bad unless it is left unused for months. PETG suffers a lot from striging so I got a filament dryer for it. Look into gridfinity if you want a desk organizer. The ikea pegboard is pretty good for wall.
