3D-printed ‘keystones’ open the door to cheap, sturdy DIY furniture

Back when 3D printing was just kicking off, there was much talk of a future where people could download new furniture designs, print them, and furnish their living rooms with new pieces whenever they pleased. Despite the fact that 3D printing your own custom-designed furniture is totally possible now, it hasn’t really caught on. This is mostly due to the fact that 3D printers aren’t a common household appliance yet, but even if they were, making a full-sized piece of furniture typically requires you to print a boatload of small pieces and snap them together to create something bigger, which isn’t very convenient. 

But who says you have to print the entire piece of furniture? Dutch Studio Minale-Maeda has devised an alternative with “keystones” — a series cleverly-designed connectors that allow you to join pieces of wood together with a single 3D-printed piece to create furniture. This way, instead of burning through a bunch of PLA filament to make a zillion different sections that snap together, you print a single keystone at home and get the remaining materials from your local hardware store.

Minale-Maeda showcased a handful of different keystone designs at Milan’s Salone del Mobile earlier this month, including ones for coffee tables, dining tables, coat stands, and a few more elaborate pieces that use two keystones. Despite the fact that the connectors are designed to work with plain, standard-sized lumber, the finished furniture is fairly attractive when fully assembled.

Is this cheaper than building furniture the old fashioned way with screws, nuts, and bolts? Probably not. If you don’t already have access to a 3D printer, it wouldn’t make much sense to drop upwards of $1,000 on one — especially when you can achieve similar results with six bucks worth of traditional fasteners. These connectors might not dethrone nails and screws anytime soon, but the future of 3D printing is definitely looking bright, and this kind of innovative design could push us to rethink how goods are made, distributed, priced, and used.

Ultraloq showcases the first-ever ultra-wideband smart lock at CES 2025
Bolt Mission UWB + NFC installed on a white door.

Ultraloq showed off two smart locks at CES 2025 -- one of which is the first smart lock to ever offer ultra-wideband (UWB) support. The Ultraloq Bolt Mission UWB + NFC uses UWB technology to unlock automatically as you approach your front door. Similar functionality already exists on other smart locks, but UWB should allow the Ultraloq Bolt Mission to be more accurate than the competition.

The Bolt Mission uses technology similar to digital car keys, and Ultraloq says it can track the keyholder’s phone location with “centimeter-level” accuracy. As your phone gets closer to the front door, the Bolt Mission can be programmed to automatically unlock, giving you a hands-free way to get inside. Better yet, because the smart lock can detect both your distance and direction from the front door, it should prevent you from accidentally unlocking the smart lock while inside your home.

Ulticam shows off three AI-powered security cameras at CES 2025
The Ulticam IQ installed outside a home.

Ulticam, the new security camera brand of Xthings, revealed a lineup of three AI-powered cameras at CES 2025. The Ulticam IQ, Ulticam IQ Floodlight, and Ulticam Dot offer not just cool AI capabilities, but also free seven-day cloud storage -- which could make them a solid choice for value-minded shoppers leery about signing up for monthly storage plans.

The Ulticam IQ and IQ Floodlight are the main attractions, as they're packed with features that should pose solid competition for the best smart security cameras from Arlo, Nest, and Ring. The duo uses edge AI to quickly identify people, vehicles, and packages without needing to upload the video for server-side processing. This onboard processing should result in faster performance -- it’s also great for privacy and security, as your footage doesn’t have to leave your device.

Home Depot expands Hubspace smart home lineup at CES 2025

Hubspace, Home Depot’s smart home platform, has seen impressive growth over the past few years, and that growth continued at CES 2025. Three new gadgets were revealed at the event, including a wireless power switch to control Hubspace products, a portable air conditioner, and a window-mounted air conditioner. All three are unique additions to the catalog -- and since there’s not much like them on the market, they should quickly become popular options in their respective niches.

The Hubspace Remote Switch is arguably the most useful of the three gadgets. Designed to look like a light switch, but with a removable remote controller, it works with select Hubspace light bulbs, fixtures, plugs, power sockets, surge protectors, and more. You’ll get standard on and off functions, plus access to brightness controls. Its sleek looks and versatility should make it a great choice for shoppers seeking an entry-level smart switch.
