Update: Have increased the size of the hole to 2mm diameter, with the bead still at 5mm diameter -> bead now prints perfectly for me at 100%

My child's bear lost an eye and so, I needed a bead (~5mm in diameter, with a 1.5mm hole) - Scale up (or down) according to the size you need.

N/B: My bead came out fine on my printer but the hole seems to have fused shut. You should get better results scaled up (or with a better printer)

v2: 5mm diameter with 2mm diameter hole (may print better at 100%)
v1: 5mm diameter with 1.5mm diameter hole
