2: Earphone Holder

Where do our earphones go when we need them the most? We all love to listen to music or watch movies or videos on our smartphones. But what makes the entire experience more immersive is a nice pair of earphones. But we always put them in some place we can’t instantly find. And even if we find them, they’ll be all tangled up — taking much time to carefully and delicately untangle the cables to make the earphones usable again.

Here’s what we suggest — use our 3D printers to create a dedicated earphone holder! The holder can be designed for rough usage too as it will be enclosable. We highly recommend creating an earphone holder for people who love to travel.

3: Headphone Hanger

Losing an earphone we can afford. But a headphone? Well, an average high-quality headphone comes for around $300-500. You don’t want to put all that money to waste, do you? That’s why we want you to build a headphone hanger with your 3D printer. We all love headphones. They offer superior audio quality and most importantly, provide excellent seclusion, especially in a noisy environment.

In other words, you ought to add protection for these big bulky boys by designing a dedicated headphone hanger to add to your work table. We suggest you go for a headphone hanger that fits any tabletop up to 25 mm thick. Since most headphones have a headband of 45-50 mm, make sure the hanger’s width is designed accordingly.

14: Hanging Planter

Two words — Elegantly Beautiful. A hanging planter is what we call a “perfect home decor.” Let’s find out why. Well, first of all, the fact that the planter isn’t taking up space on your floor is simply amazing. You can fix the planter anywhere on the ceiling and boost the elegant and modern look of your house.

Where should you hang it anyway? If you ask us, we’d hang the planter on a balcony or near a window. This is because you’d want some sunlight to fall on it. Second of all, look at the teardrop shape of the planter. It gives the feeling of the planter melting away, like water from ice. We find this 3D-printed hanging planter an awesome housewarming gift too!

16: Measuring Cube

Let’s face it. Not all of us are good at “having an idea” of how much stuff we need to add when preparing food. Indeed, the recipe magazines help by mentioning the exact amount of ingredients to be used. But how will you measure the precise amount to be added? This is why we recommend everyone to have a 3D-printed measuring cube.

What is a 3D-printed measuring cube? It is essentially a useful tool that allows everyone to measure the amount of ingredients being added while cooking. When designing a measuring cube, make sure to efficiently use the cube to add different measurements for example one cup, one-half cup, one-fourth cup, and so on. You may even design smaller measuring cubes for even smaller measurements!
