The "Celtic knot book mark" by Mememastermax is ideal for remixing to add characters to the top. Never read a book again without having a bookmark specifically designed for that book!

My grandaughter loves the beautiful unicorn design by fragar - which she has also declared that I will remix to replace all of the light switches in the house (see the wonderful duplex switch https://www.thingiverse.com/thing:3363920 by d_chall using the same great fragar unicorn.

My thanks to all 3 of the authors.

Update: Added another STL with a thicker unicorn . This gives a little more rigidity to the legs and tail

Update1/2023: I made the bookmark for my granddauther— she particularly loves it with her name on it. You can easily modify the name by editiing this in Tinkercad

See https://www.tinkercad.com/things/lXprhCqf5Hq-unicorn-cassie-bookmark or

to edit your names.

It is particularly nice to print the name in a different color.

If you need an example of how to print in multi-colors, see my 3 color nameplate at thing:4966922 for instructions on how to do that using Cura's "Pause at layer" functionality.
