This model is inspired by Jake_of_all_Trades Pulley Extractor (https://www.thingiverse.com/thing:3593964) but with changes:
fillets added (for removing failure point when using excessive force)
chamfer added (removed sharp edges for better grip)
made slimmer for faster printing
two versions with difference being bottom distance - the gap distance between pulley and motor cover when extracting (3.75mm and 5.25mm; see screenshot attached)
