This is a really simple bookmark. i looked at a lot of the book marks avilable but nothing cought me eye so i made this.

i design it to be a 20- minutes print on the a1.

it will take you 2.7 GRAMS so it will basically be free.

you need to print it like in the slicer screen shot.

you can remix the file in the .step file i provided, but you need to share it here and credit me.
