Introducing - the nifty little clip which holds your book open while you read it! This book holder fits around your thumb and is the perfect device for those who read with one hand (or those adventurous enough to read multiple books simultaneously!). I came across this idea somewhere on the internet and thought it would be the perfect thing to print. I've done my best to make it as ergonomic and comfortable as possible but naturally catering for all thumb sizes in one design is somewhat challenging - it may need scaling to fit your needs.
Model in picture printed on 0.3mm resolution, 30% infill using DaVinci 1.0 in ABS.
No need for raft/support/brim.
