Custom 3D Design & Engineering
From napkin sketch to production-ready part — designed by an Application Engineer, prototyped in-house at our Woodbury, MN shop.
QuoteWhat we do
Three specialties, one shop.
Custom Design Engineering
Have an idea or a broken part? We model it in CAD, prototype it, and refine it until it works — brackets, mounts, replacement parts, product prototypes.
Filament & Material Engineering
Not sure what material your part needs? We help you pick the right filament — PLA, PETG, ASA, nylon — and dial in print settings for strength and finish.
Bambu Lab Repair
Printer clicking, clogging, or down? We diagnose and repair Bambu Lab FDM printers — mail-in service available. Fast turnaround, genuine parts.
How it works
Tell us what you need
Send a photo, sketch, or broken part. Tell us what it needs to do.
We design & quote
We model it in CAD and send you a clear quote — no surprises.
Prototype & refine
We print a test fit, check it against your needs, and adjust.
Final production
Approved design goes to final print — one part or a small batch.
Common questions
How much does custom design cost?
Every project is different — it depends on complexity. Send us what you've got and we'll give you a clear quote before any work starts.
How long does it take?
Simple parts: a few days. Complex designs with prototyping: 1–2 weeks. We'll give you a timeline with your quote.
Do I get the design files?
Yes — you own the final STL files for anything we design for you.
Can you fix my Bambu printer by mail?
Yes. Ship it to our Woodbury shop, we diagnose it, and send it back working — or walk you through the fix if it's simple.
Have something to make or fix?
Send a photo and a sentence about what it needs to do — we'll take it from there.
