Proper scaling for the Prusa Slicer
When I import a .stl file into the Prusa Slicer, it is typically very good at recognizing that the .stl is in Imperial units and asks me if I want to convert it to Metric. I agree and off we go. But, on rare occasion, my .stl could be either Metric or Imperial so Prusa defaults to Metric. What is the best way to scale that imported part back up in the Prusa Slicer to Imperial size?

One possibility is to right click on the object and look in the dropdown menu for the 'Convert from...' options.

I usually only use metric units to design, and "m not sure how Prusaslicer imports metric units, so my advice may be off.
1 inch is 24.5 mm, so if you import say a 1 inch box and it shows up as 1 cm in size, select the part and scale by 245% so the 10 mm box is now 24,5 mm or 1 inch.
If it gets imported as 1 mm, scale by 2450% to get a 1 inch cube.

One of my peeves is when I see measurement systems being mixed: "I printed a 2" square box with 2mm walls. The room temperature was at 68F but I kept the chamber at 40C"

I like this: Scaling by 2540% works well. Thank you!

Wow! That is brilliant. Did not know that was even an option. Thank you!

Foxrun you might want to double check your conversion, 1” is 25.4mm not 24.5mm

F…ing dyslexia ! Of course you're right. Where are the wonderful AI spell checking tools when you really need them 🙂

Well, they should be in that ball you carry on your shoulders. 😀 😀 That is, unless you only have it there to mount the ears on. 🤣 🤣

Well, the easiest way to fix this problem is to embrace the metric system. Seems to work OK for 99% of the planet.

Old dog, new trick. Even though I have worked for companies that have required metric units in their designs and the metric system is more logical in many respects...I grew up with Imperial units and almost exclusively design in Imperial units...especially designing something just for fun.
