About this 3D model

this is a spool holder designed to be placed on a board of a size of 3/4 inch by 1.5 inch. (i wouldn't recommend to use spool bigger than 1kg). There is 2 files, one has holes to screw the holder, the other doesn't and is intended to be easily movable it is intended to be printed flat(the bottom is flat), brim isn't needed
