As a small business proudly owned and made in the USA, we deeply appreciate your support. We’re dedicated to providing exceptional service to ensure your satisfaction. Our enclosures come with a 100% satisfaction guarantee and a 1-year warranty against manufacturer defects. Built by 3D printer enthusiasts for 3D printer enthusiasts, we understand your needs and are committed to delivering quality products that enhance your printing experience. Thank you for choosing us; we’re here to make sure you’re happy with your purchase.

Who We’ve Worked With

3d printer enclosures for business, education, universities.

More About the Clearview Infinity Enclosure

Our main objective was to give your printer an unobstructed view from any angle. At the same time, our enclosures offer easy access with a magnetically latched front door and a cable port to route all your connections. A fitted port for your power supply unit uses cool exterior air to extend your printer’s longevity—especially useful with the optional external PSU mount.

We also have adapted options for our Carbon Air Scrubbing filter and vibration dampening feet. Both do as they suggest. The Carbon Air Scrubbing Filter uses a silent fan to pass air through a carbon filter to reduce fumes created from the 3D printing process—essential for ABS printing. Our Vibration Dampening Feet use a multi-material lamination that dissipates vibrations at 5 different levels, perfect for reducing noise in any setting.

We offer a black or Prusa Orange color option for the brackets and fittings. With your purchase, we provide STL access so you can print these fittings in your preferred colors. Additionally, we offer STL files for future attachments and accessories—if we create a mod, you get it for free!

This makes a great gift for the 3D printing tinkerer within your friends or family.
If you’ve had problems with parts adhering to the print bed, warping, bad smell, noise, or dust, this enclosure is the right answer.

While 3D printing is a fun, productive activity, it comes with nuisance factors:
-It can be loud at home.
-Drafts or temperature changes can lead to warping, print issues, and poor adhesion.
-Molten plastics release VOCs that are unhealthy, especially for kids.

Our enclosure sets up a safe, productive 3D printing environment with a sleek look. It includes all parts needed to assemble in about 30 minutes with provided instructions. The front door offers generous access to the print bed and controls, while a wide rubber grommet manages your power cable and USB. PETG parts and hardware complete the setup—start printing right away!

FAQ

What is your return Policy?

We have a 30 day return policy. Unused, undamaged panels that still have the masking fully attached are eligible for a full refund less return shipping. If panels are damaged (after shipment) or the protective mask layer has been removed, we cannot offer a refund. For best results in ensuring fitment and to ensure you like the setup of our enclosures, consider at least partially assembling with the mask on. If it’s not for you, this allows a full refund.

Why would I order Polycarbonate vs. Acrylic?

Panel choice is the only feature you can’t change later. First, 1/4" panels are our top upgrade—get them if nothing else. Polycarbonate is impact resistant, while acrylic is scratch resistant. Acrylic works for most filaments, including high-temp ones like ABS, ASA, and PC. Polycarbonate is only needed for chamber temperatures above 60°C.

Why would I go for a Recirculating Filter vs. an Intake/Exhaust Setup?
It depends on your filaments. For PLA/PETG, we recommend Intake and Exhaust filters to control temperature and vent fumes outside with a 4" hose. For higher-temp filaments (ASA/ABS and above), our Recirculating filter excels, reducing fumes and smells with activated charcoal and a HEPA filter while maintaining heat.

There are some differences between your product pictures.

We update often, and as a small business, fresh photoshoots for every iteration aren’t feasible. Function stays constant or improves. For the clearest view of the current version, rely on the renderings rather than photos.
