Fine mesh for mosquito screen not working
I have been trying to print a mesh for a mosquito screen; 1mm spacing and 0.3mm diameter cylinders to form the "threads" all drawn in TurboCad. Without supports produced a squiggly mess, and with supports there are multiple layers but not even and not to the design. Can anyone advise why this is happening. I used .stl from the CAD to PrusaSlicer.
RE: Fine mesh for mosquito screen not working
Can you please add a copy of the Project .3mf file, containing the model, so we can try and help.

RE:
While not addressing your particular issue (sorry!) I can suggest another (rather easy) way to generate a mesh. If you simply define your mesh shape as a solid object, then slice it with zero top and bottom layers, it will print entirely with the infill pattern. Define a suitably high number of perimeters (to make a strong enough border), then choose your infill pattern and infill density to vary the mesh. Not as controllable (e.g. mesh size) as your method, but by eyeballing the slicing result you can probably make a mesh to suit your needs. There are a few infill patterns that work well as a mesh - see here.

It just occurs to me that it wouldn't be better to go to the nearest garden or DIY store and buy that piece of netting. Or use an old curtain. Otherwise, there are no limits to folk creativity, as long as the print doesn't cost you more money than a square meter of the finished netting. 😀 😀

Miroslav - this is a 3D printing forum, not a life hacks or DIY forum! 🤣 🤣

"Joan; I can't upload that file format.
@Chris; thanks for the obvious solution of buying the mesh but this is for a boat's porthole which has a specific detail to position it and retain it in place as attached. I had extracted my mesh element to check the printing would work because I know the surround is OK. I could have bought the replacement item at a huge price but the challenge was to do it myself. Perhaps a bit ambitious for a newby to CAD and 3D 🙁
Thanks for the comments.

ZIP Compress the .3mf file and try again please!

For the record, that was Miroslav's suggestion. I'm totally on board with printing this!
If you have already modelled the outer frame, then I would certainly encourage you to use one of the infill patterns to make the mesh. Either model a separate co-located solid disc to represent the mesh, or use a cylindrical modifier in the slicer, and then set the top and bottom layers for that part to zero, and play with the infill settings until it looks right.

For example: 150mm x 5mm cylinder, 10 perimeters, zero top and bottom layers, 80% stars infill

Hmm - for both of the above posts I took too long to type my edits and they were lost. Third time lucky to make my point!
If you're planning only to print a new mesh to, say, glue into the existing frame, then that's even easier - no CAD involved. Start with an empty bed in PrusaSlicer, right click to add a shape, set it to the right dimensions and then adjust the settings to define the mesh. The above is an example of that.

Thanks Chris. I have done the perimeter frame but your final suggestion is simpler - I'll try that. Many thanks.

You can combine the two of course - make an STL of just the frame that you've already modelled (without the modelled mesh), then add the cylinder shape such that it overlaps the inner diameter of the frame slightly. I think you may not even need perimeters on that cylinder in that case - it would just be a slab of infill.
