What Should I Know Before a 23 Hour Print?
I have designed a large mount for my Raspberry Pi 4B 8 GiB which sits on top of this: Yottamaster Aluminum 4 Bay USB3.0 Hard Drive Enclosure (PS400U3)
The case used is the Argon NEO Raspberry Pi 4 Case. My mount design is quite likely to work as I've checked my measurements carefully. Some parts of it won't be properly dimensioned if I use a layer height other than 0.10 mm. Because of this PrusaSlicer gives the print time as 23 hours and 26 minutes, what should I know before proceeding with this print?
I've included the .stl file for the mount.

Upload STL or (better) 3MF project file
It doesn't look like your STL attached. Save your current 3MF project file, zip it up, and attach it to a reply here so we can see your part & settings and give better recommendations.
The main thing I'd recommend before starting such a print is trying a few options out that might GREATLY reduce your print time while maintaining your print quality and strength. I've got some notes here that might give you a few hints. Simply changing extrusion widths or layer heights can make a big difference in print times.

The STL File
I've been trying to attach the file but it doesn't seem to be working for me.

Did you zip it?

Basics to check
These are the obvious things to check before you start printing loong project:
- Check the your sliced model, on Prusa slicer there's a slider on right which lets you see how the print is going to happen. Check that there aren't any obvious errors.
- Check that your spool has enough plastic. In this case the job does not require huge amount of filament, but having to start over because the filament run out is not even amusing.
- If you must use 0.1 layer height because some details on the part require it, check if variable layer height would help: https://www.help.prusa3d.com/en/article/variable-layer-height-function_1750
- Ensure your filament is dry. Stringing will ruin your details properly on so low layer height.
- Printer is in proper condition? Previous parts with the same filament where ok? If you changed the filament, you might want to print a tiny model first to see that there are no issues.
- If in doubt, ask fellows on the forum what she model looks like, just like you have done.
I cannot see anything that would *require* 0.1mm layers, most cases like this are OK with 0.5mm tolerances..?
Using 0.2mm SPEED with 20% cubic infill it requires less than half the time.
Cheerio,
