i printed out the mk1 and mk2. they came out great! i printed out another blade section and more chain links to make it just a bit longer so it looks close to the correct size (in my eyes). I had to dremel out the bottom slot for the chain just a little bit wider because the gear is just slightly offset. other than that, it went together perfectly, and the chain rolls smooth. the parts I had to order from the links to Amazon made it easy to get everything for the build. the mk2 is a great print (so is the mk1). had to print out a seal and chain to make it accurate. now it's time for paint!

the print came out great! easy to assemble with a 7/16 wooden dowl running down the inside
