Book Page Holder - Thumb Ring

This is my entry for the ring competition. It is a thumb ring to hold the page open. 

Version 1:

The thumb hole has a diameter of 26mm, if you require bigger let me know and I'll add in some bigger or smaller versions. 

I printed with 10% infill and Ironing of the top surface. Circa 44 minute print time. 

Version 2.0 (Sstachu Special) :-)

A U-Shaped area for your thumb to go. 

I must still print and test this one out.

I will print at 10% infill (rectaliner) and 4 perimeters. - Circa 1hr 6mins
