I miss TechShop, too. If making is your passion theres good news: it isn't dead. Current virus issue excluded there are many smaller maker spaces you can join in the bay.
I have small tools. TechShop had the big stuff - CNC mills, waterjets, plasma cutters. I used all of those. The smaller maker spaces are at the low-end 3D printer level. Maybe a wood shop. There's Humanmade in SF, which has much of the old TechShop gear, but it's an hour away and twice as expensive as TechShop.
