My roommate and I got bunk beds recently so that we could get more space in our dorm room. It's worked out great so far, except the one problem I have on the top bunk is that I have nowhere to put my phone at night since I need it close to wake me up and I don't feel comfortable just having it sit on the bed next to me since I'm 10 feet off the ground.
So I decided to make this. A shelf that fits onto the side of the bed frame. I designed it for my phone, which is an iPhone 6 with an Otterbox, so it should fit most phones pretty easily.
I've only printed the original, not Phone Shelf 2, so far. I realized after I finished printing the first version that having a little indent to make it easier to pull the phone out and to make more space for a charger would be a good idea, but it really isn't a big deal to not have it so I don't think I need to use the extra plastic to make a whole new shelf. I see no reason why those changes would cause any problems when printing though so long as the indent is at the top.
The hook for the bed frame is based on the bed in my dorm room which is probably not the same as every bed ever, so I uploaded a .step file for each one so that other people can modify it as they need to. I'll probably upload another version at some point that you can just tack onto a wall. You may need to scale the .step file up to ten times it's original size since Inventor has a tendency to export CAD files at a tenth of their original size for some reason. So if you try to modify it and it seems small, that's probably because it is.
For the original version I used PLA with 12% infill and 3 shells at a resolution of 2.5. I would recommend the same for the second version since you don't want this to snap on you.
I'm using simplify 3D now so I can manually place supports on the print and I did decide to place a couple in the space for the phone since the distance for that wall looked too big to bridge. It's up to you if you think you need them or not.
Sort of a side node, be careful with the corners on this thing, I scratched my arm a couple of times on the corner of the hooks. Not a big deal, but it's happened enough that I figured I'd warn everyone.
