I improved the already existing amazin chess set made by Jackson Richey (https://www.myminifactory.com/users/JacksonRichey).
Added a base for all the pieces for better printing and uniform looks and adjusted the sizes.
After several prints, i found out that the following sizes are optimal (X x Y x Z in mm):
All Printed in PLA+ with 0,2mm layer hight, brim & supports in critical regions.
Have fun with it :)
