I’ve just preordered a Maslow and have started thinking about what functionality I want from it, particularly with the frame. I do not have a lot of space and bounce around between work spaces quite a bit, so I really want something that I can breakdown for easy transport.
With that in mind, I came up with this idea for a frame system:
I like the idea of being able to fit the whole Maslow into one crate or container, so I focused on making the frame of pieces no longer than two feet. I also wanted it to be modular so that the frame could be shortened if the work space only allows for use with 4’x4’ sheets.
The part I feel pretty good about is the modular beam. I designed it to be constructed from 3/4" plywood laminated together. In simulation, the beam is able to handle the loads in normal use (I used 75 lbs) with almost no deflection. The entire beam, with the exception of the brackets and maybe the motor mounts, can be made from a single 2’x4’ sheet of plywood.
I wanted to use aluminum tubing for the rest of the frame to save weight, and I found this aluminum tubing/connector system that I think would work well. They also have aluminum tubing with flanges that could be used to support the waste board and material. This would eliminate the need to add extra bits like a 2x4 across the bottom. This tubing system is used in structural applications like trade show booths, tables and display cases, so I think it will be sound enough for use with Maslow. I’m not positive that this is the best direction for this part of the frame, but it seems decent enough.
I wanted to put this on the forums to see if you all had ideas about this as to whether or not it would work or any improvements to it.
I also wanted to share this because I feel that thinking in this direction could help the goal of using Maslow to fulfill needs in various communities, which is what immediately drew me to this project. Developing a complete Maslow that can be packed up and moved easily would be very helpful in getting this tool to communities that need it. So if anyone has any ideas towards this goal, I would love to hear and discuss those as well.
