These are a work in progress… wanted to post them before the end of the month. 
You can put your custom design on the ends. I did the assemble in fusion 360 but have not cut them yet so user beware. I was waiting to post them till I was able to cut them to make sure they worked and so I could post some pics but I won’t be able to get to if for a bit.
Collapsible fire pit. You need to cut 2 ends and both side 1 and 2

I have always enjoyed cooking on a Swedish fire torch and/or log rocket stove. In the past I have used grille I made of rebar. Thought it would be fun to design and cut some. I have held off on posting these as I wanted to post with pics but haven’t had the time to cut them yet.
For the rocket stove you will need to bend the 8 spikes over to hold the grill up above the top of the log to give the fire some breathing room.

For the Swedish Torch you fold the 4 tabs down to create the space between the log wedges. split a round into 4 pieces and wire them together. The holes are for 12" spikes to hold the log pieces together.
