This is, in fact, just a (more expensive) version of 80/20 Ready-Tube with a wooden option, which is really nice (80/20 is aluminum only). It should be compatible with existing 80/20 hardware.
Wow, I made an account to download the BoM and that coffee table’s total price of materials is $1108 and the end table is $1378. I was expecting less than half that.
If I have to almost design my coffee table from scratch, including sawing all the pieces to length, then I don't really expect the parts to cost much more than $30. The real investment was my time...
They’re not cheap, but they have engineers on staff who will help you finalize your project.
I’ve used them for several things in the past and have been quite happy.
