Hello there!Starting with september 2025 the 300ppi gridded PDFs will be discontinued.This is partly because they take a away a lot of storage space on the cloud and because it seems it isn't a feature that get's used very often.That's why you won't find them on the Cloud anymore.But to give you a possibility to get access to the ones that exist anyway I created this Archive post where you can download them.
If you want to create PDFs for printing with later publications I can recommend the "PDF 24 Tools": https://www.pdf24.org/ I used it for my PDFs as well and it's completely free to use. For those I recommend to use the 300ppi jpg Map files since they have the proper resolution and size for printing. If you use the PDF24 Tool: You should check if the Inch size is correct if you want to print them and might have to change an export setting if they don't:Go to "Convert to PDF" > "Settings" (In the footer) > "Images to PDF" > change DPI to 300 (and use the 300ppi jpg images as source for your export)Now you can just drag & drop the images you need and convert them to PDFs.
I hope you'll eventually find use for these!You can download them by clicking the attachment below.
