<p dir="ltr">If a centre hole is acceptable then you could use a hole saw. I have had good results cutting ABS. I used a good quality arbor and saw with 3 cutting teeth, not the ones with serrations.</p>

I am looking for disks about 50-70mm dia, 5-15mm thick, and about 100<br>
of them... I need a notch and 2 holes in them too, but that's easily<br>
taken care of.<br>
<br>
The straightforward option would be to slice up a 50mm dia wooden pole<br>
or dowel, but plastic would be better because of the lower weight.<br>
Perhaps something like a tooth wheel from a mechanical toy set. The<br>
teeth on the disk would not be a problem.<br>
<br>
Getting it laser cut is likely not cheap enough, and solid plastic<br>
probably weighs more than pine too.<br>

Has anyone come across something suitable that might be put to use with<br>
a bit of drilling and hacksawing?<br>
