that is absolutely impressive! I don't see any strings from here. Do you need any beta testers?

For the record, your mod has been the most accomplished piece I have seen since Chopmeisters Nanoblock regarding direct drive extrusion with the Ultimaker 1. I consider it the next logical step after bowden extrusion, it just enables you to do so much more with a simple machine. So many different materials to test! I am very excited about your work, keep at it! I don't know if you know the hyena bolt of shop.arcol.hu, and its owner László Krekács, I had his Bolt running in one of my U1 back when I was a student and it worked very well, maybe you could ask him to machine a custom drive gear for your build, with your specifications, his prices are very reasonable and he seems to be an overall nice guy. I did a humble homage to your work in order to adapt my newly purchased E3dv6 Hotend to your modular printhead design, I posted it in youmagine, for some reason I cant open youmagine so the link will have to follow soon. Again, thank you for sharing your amazing work !
