I got the Ostrich Egg-bot in the mail last night and assembly went smootly until some of the metal brackets would not allow anything to screw into them. I couldn't twist the thumb screw hard enough and when using the driver on any of the socket screws the driver would twist as opposed to the screw moving. I gave up frustrated last night knowing if I continued I would break something. With a clearer mind this morning I got my tap and die set and recapped the annoying angle brackets, 7 holes in all. Aside from that it was a fun and enjoyable kit to assemble and is working fine.
