What is Protocase Designer?

Protocase Designer is free 3D CAD software that makes designing a custom enclosure, panel or component extremely easy. The software offers dozens of templates for enclosures, panels and brackets, each customizable by material, size, color and more. Choose the template that matches your requirements, then immediately begin working with a blank 3-D model. Start editing by adding cutouts, mounting hardware, labelling and graphics until your design is exactly how you want. At any time in your design, get a real-time instant quote. When you're ready, order your design online and we'll build it in 2-3 days, with no minimum order.

What Our Customers Say

"From the start, your software was easy to pick up and learn (being that I work with Creo on a daily basis, it wasn't difficult), to the ordering process - it all went smoothly." Brian F. Massey
John Hopkins University
"It is a great tool to work with, simple yet straight forward interface, very easy for beginners. I was able to start a new design just in minutes. I like the cut-out libraries a lot, which further reduce the design time and processes. It took me about half an hour to finish the design that was sent to you for manufacturing." Juanjuan Liao
TRUMPF Inc.
"We originally started designing the dock system using Solidworks CAD software. Once we realized the abilities of the Protocase Designer software, we switched entirely to designing these pieces in Protocase Designer." Michael Spinelli
StrongArm Technologies
"Without ever using [Protocase Designer] software before, I was able to use the 3D viewing capabilities to easily select and customize the enclosure template that best fit our needs. Everything worked great, from order acknowledgement through to shipment - Protocase has been really great to work with." Mark Dudzinski
Light the World
"The majority of the design work was completed using Protocase Designer, as it's quick and easy to use. When there have been complexities to the design not covered by the software's templates, Protocase has been very flexible in the ability to work with emailed descriptions, sketches or other CAD system files." Rich Littlewood
Diamond Light Source
