Introduction
Hello, and thanks for looking at my model.
I debated posting this or not as it may not be directly usable to too many people but in the end I thought it might at least be a good example of what's possible. We see a lot of genuinely pointless, if fun, things in 3D printing. Far more than utilitarian things anyway. Even many of the utilitarian bits are focused on pretty decor, like decorative wall shelves or vases and the like or on the other end reimagined tools like router templates or game rulers.
This is a strictly unfancy, undecor type project made to fill a simple need. I resurfaced our small bathroom for my wife to make it newish until I have the time and money to gut it year after next. Part of that was a new medicine cabinet with a frameless beveled mirror. Knowing I was going to rip it out in a few years I was not up to spending top dollar on it. I got one of the injection molded plastic ones at depot for less than fifty bucks. It's one of the ones with three preformed shelves you can't change around. It's meant to be installed with the big shelf on top and the door opening on the left. This did not suit our bathroom and the big shelf being on top made no sense. I installed upside down and it works much better for us.
The issue is that big shelf now in the bottom. It's not tall enough to stand toothpaste on end and leaving the different tubes just piled up is a mess that keeps falling out when you try to get something. The answer was this shelf. I printed several test rulers to get the measurements correct and radius gauges for all the competing radii that join together on the side and back. There is also a small indent on the side against the medicine cabinet to allow it to sit flush with the side and make room for the head of the mounting screw there. I split the area into three shelves and a tall section at the right where packs of tablets you drop in water for dentures overnight can be stored without falling out.
Each shelf has a small raised lip at the front to prevent things from just rolling out easily. There are different heights for the shelf at the back and at the front and different radii everywhere. I used a small piece of self adhesive velcro on the back to keep it stuck to the cabinet so it just doesn't pull out of the smooth plastic but can still be taken out to clean periodically. There is also space to the right of the shelf that makes room for a small cup that takes up most the height for tweezers and such. This was a great project as well to help learn different ways to make complex and compound objects in Solidworks.
Printing
Material: PETG
The MK4S will not print an object this big (takes up the entire print bed) correctly out of ASA (the technically correct material for this) as the material is well beyond the printer's capabilities. Printing it in PETG came out perfect the first times after several failed attempts in ASA. Accordingly the 3MF file is set to the Generic PETG profile. Change it to brand specific or another material as you choose. PETG is what water bottles are made of so it should put up with whatever little bit of moisture the medicine cabinet will get anyway.
Infill:
Gyroid 20% - I know some may consider that excessive but it's a fairly long shelf of plastic and I didn't want it to bend. After woodworking forever I still have a hard time trusting thin plastic for strength. Sue me.
Supports:
None are need if printed flat on its back like in the 3MF. The lips at the front of each shelf are at 45 degrees and will print just fine without supports on any printer. Yes the radii are not going to be the smoothest but they are required to get it to fit properly and they are never going to be seen once the shelf is in place.
