Being a student space is very valuable in my kitchen. This trivet can be used for pans and pots of different sizes, without needing a huge amount of storage space.
Btw this is a great gift for mums and grandmas.
Step 1: Basic concept
You can of course connect more than one piece to another.
In one of my earlier tries I've used round 2x2 lego plate to connect the pieces, like probably you I wondered, whether the plastic is stable enough, but no matter how hard I tried I couldn't get it to melt, by placing hot pots and casserole dishes on it. This is not to surprising, because wood is a pretty good insulator and because of the holes between the disks a heat accumulation is prevented.
But the connections weren't strong enough and it kept falling apart.
