When I moved the PSU down below, it left an obvious opening for improvement. I built this from another one I found on another site but can't find it now (when I find it, I'll link the re-mix).
You'll need supports for the bottom (or side if you can print that tall - my printer said it was quicker to lay it down).
I only had 8 bolts, so I only used 8 of the fastener spots. This really firmed up the Z portion of this printer (wasn't very wobbly before. Not it is sturdy'er. My Anet A2 on the other hand .. is SO wobbly).
I printed mine with PLA .28 layer height, 5% grid infill, supports over table, and let it rip. I may print another one that's finer detailed with more infil, but this is a simple, utilitarian print for one job, and it isn't that noticeable the way my printer is sitting.
I plan on tinkering with it down the road and making it more usable for tools, hooks, hangers, storage, LED location or something like that.
