Score keeper for darts. Each of the 3 sections is 190mm x 145.6mm for a total size of 190mm x 436.8mm. The first one is Bull-15 if you only want a score keeper for cricket. There are countersunk screw holes for mounting. I just used carpet tape on mine Numbers and scoring marks are .4 from the bottom. I printed at .2 per layer and did a filament change at the 3rd layer. There are 3 scoring marks and an identical but shallower mark to the outside of them. They're otherwise identically sized and spaced if you want to modify the scoring sliders to positively index in each position. On my Ender 3 S1, the skirt will print across the same space as my priming lines. I just peeled mine off while it was printing.
