how to upscale a 3d file to match my measurements
Hi all,basically, i have downloaded this file https://www.thingiverse.com/thing:3723903 and need to upscale it to fit a 60ml syringe.it's for my great nan as she has to be fed via a feeding peg and she struggles to plunge the syringe when full of her feeding liquid.i have no idea on how to do this, i have the syringe with me and some calipers but no idea on how to use them any info would be much appreciated

Suggestion...import the STL file into your slicer and you should be able to adjust the size there up or down ready to export it as a G-code file.

@TayZc1, I found an amazon item that presents the dimensions: https://www.amazon.com/Pack-60ml-Syr.../dp/B07H3MH52R If you can confirm that these values match the item you have, it provides a starting point. Using the 20 ml model in the link you provided, I measured the opening for the syringe. It appears that the 20 ml syringe requires about a 21.5 mm diameter to fit in that model. The amazon link indicates a 31 mm diameter, which scales up by 144 percent. It's possible that you'd want to go a bit larger, perhaps 145 percent, but too much could create slop in the design. At least with upscaling a part, it becomes less fragile as a result. Using the 144 percent figure, I've scaled the objects using Meshmixer and attached them. Obviously, you'll want to ensure that the length is appropriate. That's a parameter I did not check. I'm hopeful that adjusting the inside diameter of the female portion will provide for proportional matching of the syringe.
Printer will print perfect...
