Laptop Stand to fit a Lenovo Legion Y545

Disclaimer: This was designed specifically for the Lenovo Legion Y545 Laptop, with very close fit; the laptop fits the stand like a key fits a lock. I do not know if this stand will fit any other Laptop, including the newer Legion series. Thus, your mileage may vary.

I needed to lift my laptop up off the table and raise the screen to eye level; the laptop sitting on the table as a laptop typically does was enforcing bad posture and causing unnecessary neck and back strain from having to look down all the time. This chonky guy is the fix for that problem. 

Yes, it could be thinner walled, but I can't afford a new laptop if it falls and breaks due to a laptop stand failure because I chose to save a dollar worth the material, so I made sure this thing would not only be sturdy, but would have retention that would act as a keyway and fit the sides and deck/wrist rest of the laptop like a glove (with 4mm of clearance between the wrist rest and the retention roof) while also leaving the side I/O accessible. But while this keeps the laptop perfectly and securely in place, it prevents the lid from fully closing. This is not a problem for me, the lid stays open most of the time unless the laptop is stowed. Just the same, I made a version of the sides with top-open retention so the lid is fully closeable, should you want that. Options are cool, after all.

Included is a 3mf of my Orca Slicer print project so you can use my print orientation (and/or settings). The crossbar (03 Center) just fits on the build plate of the Bambu Lab X1C at an angle. My test prints were in ABS and I had some issues with Orca sending the correct files to the printer (IDK what was going on with Orca), and I didn't want to waste material re-printing the correct files when I was going to glue the parts anyway, so the fit may be off by a couple tenths of a millimeter. You may want to print just the tip of the crossbar where it slots into the sides for a test fit, and do a +/- 1% scale in your slicer where necessary. Sorry about that, I'm being lazy on this one.

My print settings were overkill--I think I printed this at 6 walls, 20% Cubic, 0.2mm LH, support on, and the Top Support Interface Layers and Bottom Support Interface Layers both set to zero; your supports will just pop right off like magic with very little surface cleanup. Keep in mind, printing slower will likely improve overhang surface quality. As for strength, 3-4 walls would likely be enough, I don't think you'll need 6 walls. 

You will need two (2) of the crossbar, and they need to be glued to the sides (CA glue worked fine for me). I used 2mm adhesive-back craft foam for feet, for padding in the retention area that the front edge of the laptop presses against, and for grip under the laptop (works wonderfully).

I am seriously considering making a Cooler Module with some small fans (a couple 4010 fans would probably work, but I may do 5051 blowers). I have a handful of fans from old 3D printer upgrades and as spare parts, and I kinda want to see if I can pull it off and wire in a USB cable to power them. I'm also in the process of designing a drawer unit with three drawers on either side that utilize the empty space inside of the stand (under the laptop). I may or may not publish it; I need to redesign it to use less material (it'll use almost 2kg of material as is).

Happy printing, and remember, my settings work great for my machine, but your mileage may vary.
