***OH WOW, LOOK ANOTHER ARROW SQUARING TOOL*** THERE ARE A NUMBER ONLINE BUT THIS ONE SEEMS TO OF DONE THE TRICK FOR ME, DRAWN UP IN FUSION, JUST INSERT A STRIP OF SANDPAPER INTO THE THIN SLOT AND TURN THE SHAFT UNTIL THE END IS NICE, CLEAN AND SQUARE. WAS DONE WITH THE V-CUT OUTS AS THIS ALLOWS IT TO BE USED WITH ALMOST ANY SIZE CARBON SHAFT YOU ARE USING, AMD WILL ALWAYS BE CENTRED. THIS IS MY FIRST PUBLISHED MODEL SO GO EASY ON ME, OR DONT, I DONT CARE. 

**ENSURE YOU ALLOW TO COOL ON THE PLATE TO ROOM TEMP TO AVOID WARPING. THIS IS PRINTED IN PET G BUT I DONT SEE WHY ANY OTHER FILAMENT TYPE WOULDNT WORK JUST FINE. SIZED FOR A1 MINI ENJOY
