Thinking about making a resin 3D printed Diesel 10 with Pinchy 👀
Question for you all:
Should Diesel 10 be printed with a detached face or a fixed face?
Detached face = more customization
Fixed face = cleaner, ready-to-display look

Why 3D Printing Flip-Face Parts Isn’t Viable (Based on My Testing)

I ran several durability tests on small flip-face parts before considering making them for myself or selling them.

The part shown here is the flipper (actuator) — the small lever that physically pushes the revolving face. Even though it looks simple, it carries all the load every time the face flips.

During testing, the part consistently failed at the flipper tab, not the shaft. Mechanically, the tab acts like a tiny lever, concentrating bending and impact stress at its base. At this scale, FDM 3D printing introduces layer lines that become natural fracture points under repeated use.

I tested this using PETG and ABS. While each material behaved slightly differently, the failure mode was the same: fatigue cracks formed at the base of the tab and eventually caused it to snap. Changing material helped only marginally — it did not solve the underlying problem.

In real-world play, kids don’t flip faces gently or consistently. They apply uneven force, rapid cycling, and occasional impacts. Under those conditions, a printed flipper may survive hundreds of cycles or far fewer, depending on how it’s used — but the lifespan is unpredictable.

It may last one month or six months.

Even with reasonable dimensions, printed parts failed well before what I’d consider acceptable for reliable play use.

This is why commercial flip-face toys rely on injection-molded parts rather than 3D printing. Molded plastic is continuous, has no layer lines, distributes stress more evenly, and survives repeated real-world use.

Based on my testing and experience, 3D printed flip-face mechanisms are best suited for display purposes or very light, careful play only. This is why I’ve decided not to risk selling them. Parts will break.

This is about what I’m comfortable putting my name on.
