4 Inch Soil Blocker
thingiverse
I built a 4-inch soil block maker because I refused to spend $95 on the steel one. It's perfect for my small garden plot where I only need a light-duty version. This DIY model doesn't have a spring, but it gets the job done just fine. When making blocks, you can grab either the shell or the plunger stem and start working. This is what the commercial version looks like: https://www.johnnyseeds.com/tools-supplies/seed-starting-supplies/soil-block-makers/hand-held-1-soil-blocker-9016.html?cgid=soil-block-makers#start=1
