The US just elected a child rapist, and convicted felon, who praised Hitler’s generals and said he wants to be a dictator. Oh, and he also wants to ahave everyone who ever stood against him murdered. Only 30% of eligible voters actively tried to stop it.
If you thought the Dems were conservative before, just wait and see how far right they can jump in order to chase the only group that will show up to the polls every damn time, no matter how stupid, or how fake and repeatedly disproven the reason is.

Because leftist policy doesn’t bring anyone to the polls other than the right. Only 30% of eligible voters bothered to show up to polls and vote for a black/Indian woman over a Hitler wannabe. That means that a full 70% of eligible voters said they were fine with, or were actively choosing, a child raping felon, who outright said he wanted to execute anyone who ever opposed him and praised Hitler’s generals.
You can god damn well bet that the people running the Democratic party learned a lesson, and that lesson is that so called liberals will always come up with an excuse not to vote no matter how dire the situation, but conservatives will show up even for made up shit that has been repeatedly proven to be wrong.
And if you thought the Dems were conservative before… well just wait and see how much farther right they are going to go now chasing the only votes that bother to show up to vote.

Print with larger holes, but then use multiple layers. Like Russian nesting dolls, but each “doll” would be rotated very slightly.
Also, try slots in opposite directions. Horizontal slots nested inside vertical slots would effectively create a mesh.
Flat panel inserts could be printed easily and then slid into a circular holder.
