New to Blender for 3D Printing? Avoid These 5 Mistakes

If your 3D prints don’t fit, fail partway through, or just don’t behave the way you expected — it’s not always your printer. Most likely, it's your model.

In this video, I break down the 5 most common mistakes beginners make in Blender when designing for 3D printing, and show you how to fix them with a print-first mindset.

00:00 - Intro
00:53 - Applying the Scale
02:25 - Tool Overwhelm! (Sticking to one project)
03:25 - Non-manifold geometry (gaps, and how to fix them)
05:39 - Overhangs (learning good modeling techniques)
07:14 - Rushing Your Workflow (understanding iterative design)
08:25 - Outro

These are mistakes I’ve made myself — and fixing them will save you time, filament, and frustration!

What This Video Covers:

• Why Blender’s scale must be applied before slicing
• Using the right Blender workflow for 3D printing
• Non-manifold geometry and invisible model errors
• Designing with clearance so parts actually fit
• Why iteration matters more than perfection

This video is designed for people using Blender for 3D printing; not animation, games or renders.

If you’re building things like dice trays, deck boxes, dice towers, organizers, or other functional prints, this will make everything easier!
