THE DIGITAL PLAN
The plans. Your printer. Your build.
Buy the digital design once, then source the components and build at your own pace.
What you get
3D-printable speaker files, build documentation and parts information for this design.
Your digital files are emailed after checkout.
What you supply
A suitable 3D printer, filament, tools and the physical components listed in the project guides.
The plan price does not include physical parts or an assembled speaker.

Explore the project
The speaker you’ll build, its requirements and the original project guides.
Build a center speaker that hits above its weight. Purpose-built for your home theatre front row, the Glow 4c nails crystal-clear dialogue and surprising bass grunt, all inside a 3D-printed enclosure you craft yourself.
Hear Every Line
A silky-smooth 25 mm soft-dome tweeter keeps voices razor-sharp, while dual long-throw 4-inch woofers fill out mids and low-end effects with confidence. The result? Speech that cuts through the action without sounding thin.
Slim Footprint, Easy Fit
Measuring just 140 × 322 × 186 mm, the low-profile cabinet slides neatly under your telly or projector screen, freeing up shelf space without skimping on output.
Make It Yours
Choose any filament, colour-match your decor, or print a bold accent piece—thousands of material options mean the Glow 4c slots straight into your room’s vibe.
Straightforward Print & Build
Step-by-step guides, dialed-in STLs, and a parts list that won’t break the bank make assembly a Saturday-arvo project, not a semester-long slog.
Build it your way
Build a speaker using a tested design, choose your finish and source the listed components yourself.
Printable Crossover Board makes positioning components effortless.
Labels and guides help eliminate wiring mistakes.
Filament required per speaker: 1900g
Minimum printer build volume: H175xD205xW140mm
A few things to know
How do I receive the plans?
Your digital files are emailed after checkout. Download the files and read the project guides before starting your build.
Are any physical parts included?
No. This is a digital plan. You source the components, filament and hardware separately, then print and assemble the speaker yourself.
Will this work with my printer and parts?
Check the printer build volume and component list for this specific project. Requirements vary between designs, so confirm that your printer fits the parts and that you can source the listed components before buying.
