Lazy Susan 160 v3.0

**Fully 3D Printed, Snap-Together, Conical Bearing Turntable — 160mm**

A larger, smoother, fully 3D printed Lazy Susan built for more load capacity and stability — no metal hardware, no supports, and no compromises.

This is the 160mm version of my Version 3 radial bearing system, featuring redesigned conical rollers, improved carrier geometry, and reduced binding and friction.

**Why I Designed This**

Most printed Lazy Susans rely on loose balls, straight pins, or added hardware. They work, but they're often noisy, inefficient, or inconsistent in FDM.

I wanted a fully printable radial bearing that:
- Rolls correctly without kinetic mismatch
- Reduces side rub and binding
- Prints cleanly without supports
- Snaps together easily
- Scales properly across multiple diameters

Version 3 refines roller retention, conical alignment, and carrier geometry into a smoother and more efficient system — and the 160mm size increases stability and load capacity over the 120mm version.

**What's New in Version 3**

- End-captured conical rollers (no side wall rubbing)
- Tilted conical alignment for improved race geometry
- Larger bearing diameter for quieter operation
- Flat carrier interfaces to reduce resistance
- Redesigned lighter carrier ring
- Completely flat base bottom
- Optional reduced bearing count for ultra-quiet mode

**How It Works**

This design uses conical rollers tilted by half the cone angle. This creates:
- A flat bottom race for smoother rolling
- A steeper top race for cleaner FDM print geometry

The rollers are retained at their ends using small indents and carrier nubs, eliminating side rub and reducing noise and binding.

The carrier must be installed with the connecting bars facing upward. Orientation matters.

You may assemble using:
- Full bearing count for maximum load capacity
- Half or even 1/4 of the bearings for quieter operation (reduced load capacity)

All parts print separately and snap together. No hardware required.

**Important Notes – Bearings & Print Quality**

- The conical bearings are specific to each size model
- Bearings from one diameter (120, 160, 200, etc.) will NOT work correctly in another size
- Do not mix bearings between models
- Always print the bearings included with that specific version

---

**Slicer Note – Seam Settings Matter**

The conical rollers perform best when the outer surface is smooth and consistent.

- If your printer produces very clean walls, no adjustment is needed
- If you notice a strong vertical seam bump, you may feel a slight rhythmic tick as the roller turns
- Switching seam placement from "Aligned" to "Random" often reduces the noticeable bump
- Reducing seam prominence improves smoothness and noise performance

A clean outer wall on the rollers makes a noticeable difference in rotation quality.

**Print Settings (Recommended)**

- Nozzle: 0.4mm
- Layer height: 0.2mm
- Walls: 4 perimeters (1.6mm)
- Top/Bottom: 5 layers
- Infill: 40% for all structural parts — 100% for bearings
- Supports: None required
- Wall generator: Arachne recommended

Bearings operate noticeably quieter when printed in TPU. All other parts print well in PLA.

**About the Included 3MF File**

The 3MF is pre-configured and ready to slice in Bambu Studio. Plates are organized by part group, filament slots are pre-assigned, and per-object infill settings are already applied — bearings at 100%, all other parts at 40%. Just open, verify your filament assignments, and slice.

**Available Sizes**

This design is part of a scalable family. Other sizes — 120mm, 200mm, 240mm, 280mm, 310mm, and 340mm — are available on my profile.
