I used a Lulzbot Taz 6 at the public library to print. At 2.5mm (Standard) Cura setting. Took about 3 hours.
I used the wrench to cut nails and put it together. It was not hard to put together. I found nails that were about the right size and used those, cutting them to size with the wrench.
The only problem I had is that the Lulzbot printed the center support piece slightly warped. I never saw this before.
It was still close enough to work.
Suggest printing at highest resolution or scaling the size up (probably a good idea) to make it easier to use.
A fun print. Thanks.
