If you mix: M2、M2.5、M3 、…all in one project.

Assembly became a nightmare.

Now I standardize thread sizes wherever possible.

Maintenance becomes dramatically easier.

Acrylic looks amazing visually.

But long-term: cracks too easily，edges chip

Now I much prefer:

PC

POM

nylon

Way better durability overall.

Most designers prefer direct threading everywhere.

Then after repeated disassembly:

some aluminum threads started wearing out.

Now for high-maintenance parts, I increasingly prefer inserts.

Much more reliable long term.

I used to love bead blasted anodized parts.

But after using them long term:

• fingerprints show up everywhere
• dark colors age badly
• edge wear becomes super obvious

Now I honestly prefer brushed finishes:

• feels more “industrial”
• hides wear better
• looks more consistent over time

Especially on silver parts.

Back in school,

CAD just meant “can I model this?”

After actually making CNC parts,

I realized the real question is:

“can this be manufactured efficiently?”

A lot of designs:

look fine in CAD,

but machinists absolutely hate them.

That’s a completely different mindset.

Standardization saves a huge amount of trouble.

Things like:

• standard plate thicknesses
• common drill sizes
• standard threads

Not only cheaper,

but much easier to maintain later.

CNC machining lead time isn’t just about “how fast the machine runs” — it depends on several real production factors behind the scenes.
So here’s a question for you 👇
Which factor do you think is the most influential?
