Cup Holder for Handrail: 3D Models and STL Files

This collection gathers STL files for cup holders that attach to handrails, pipes, desk edges, and car interiors. You can compare clamp designs, rail diameters, and mounting styles before opening a model page. It helps narrow a 3D printing search when you already know where the holder needs to sit. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Cup Holder for Handrail: 3D Models and STL Files»

Rail-mounted holders are built around a round clamp, so they differ by the pipe diameter they accept and by how the cup sits above or beside the rail. Desk-edge versions use a flat jaw or screw clamp and often split into a bracket plus a cup ring. Car interior designs clip to doors, windows, or vents, while modular versions add slots for phones or a second cup.

When choosing a model, check the stated clamp range, inner diameter, wall thickness, and number of parts. Look at whether the author lists supports, material, layer height, and infill, and review photos of real prints to see how the clamp closes. Consider the load direction: a cup pulls down and outward, so the mounting face and fastener points matter.

To refine the search, try synonyms such as drink holder, mug holder, rail mount, pipe clamp, handrail bracket, clamp-on, and clip-on. Combine them with a location like boat, car, desk, door, vent, or table edge. Related topics include tumbler holders, bottle holders, and phone holder add-ons for the same mounting point.

FAQ

Frequently asked questions

How do I choose the right clamp size for a handrail cup holder?
Measure the outer diameter of the rail or pipe first, then compare it with the clamp range the author lists. Check whether the design uses an insert or a shim to fit slightly different diameters.
What material do authors often list for a rail-mounted cup holder?
Authors often list PETG, ASA, or ABS for parts exposed to sun, water, or heat, while PLA appears in indoor desk designs. The model page is the place to confirm the material and settings the author used.
Do these cup holders need supports when printed?
It depends on the overhangs and how the clamp is oriented on the build plate. Some designs split the clamp and cup ring so they can print with fewer supports; check the author's notes and photos.
Can a desk clamp cup holder be used on a boat handrail?
Only if the clamp range and jaw shape match the round rail. A desk holder usually has a flat jaw for a table edge, while a rail holder needs a curved or round clamp. Compare the dimensions before printing.
