Snoopy Cup 3D Print Accessories: Straw Topper STL File List

Lisa Ernst · 30.07.2026 · 3D Printing · 11 min

Searching for a Snoopy cup STL usually means one of two things: a small straw topper that fits a reusable cold cup, or a themed accessory sized for a wider Stanley-style straw. The difficulty is not finding images of cute toppers; it is finding a specific model page that clearly states the file type, opening size, price and usage terms.

This list collects direct pages for free and paid Snoopy-inspired straw toppers in STL or 3MF format. It also explains how to check the fit before printing, which settings work for small multicolor accessories and what to consider before selling physical prints. Prices and availability were checked on July 30, 2026 and can change.

Quick answer: the best Snoopy cup STL and 3MF files

• Best free option: the MakerWorld Snoopy Straw Topper with a stated 10 mm opening.
• Best for two straw sizes: the TeoRk Cults3D files supplied in 8.5 mm and 10 mm versions.
• Best for multicolor printing: pre-painted 3MF files from TeoRk, AG Creations and TheCarrieFiles.
• Best simple flat print: the Dulceideas STL and 3MF topper designed to print lying down without supports.
• Best seasonal variation: Halloween, clover and sleeping-Snoopy designs.

Snoopy straw topper STL file download list

Every link below opens a specific model or product page rather than a marketplace homepage. “Free” and listed prices reflect what the source displayed when this guide was researched. Open the page again before downloading because creators can change pricing, file contents and licenses.

For a broader comparison of repositories, see the 33D guide to the best STL file sites. Aggregators are useful for discovery, but the final download should always come from the original model page so you can read the creator’s current license and print notes.

The official 2025 Starbucks and Peanuts cold cup used a smooth flat lid and straw. A printable topper must match the actual straw diameter rather than relying only on the cup brand name.

Which Snoopy cup topper should you download?

Choose MakerWorld for a free first attempt

The MakerWorld Snoopy Straw Topper is the most straightforward free starting point because the listing states a 10 mm hole and describes the model as a quick print. That makes it useful for wide reusable straws and many Stanley-style setups. The creator also warns that multicolor prints may need higher flushing volumes and a larger prime tower to reduce color bleeding.

The Mrs. Snoopy and Halloween variants are useful when the standard pose is not the look you want. Treat the displayed print profiles as a starting point, not a guarantee: confirm the actual file dimensions in your slicer before printing.

Choose the TeoRk files when fit matters most

The two TeoRk Cults3D listings are unusually clear about sizing. Each includes an 8.5 mm “Standard” version and a 10 mm “Stanley” version in both STL and pre-painted 3MF formats. The regular Snoopy model is roughly 36 × 44 × 16.8 mm, while the sleeping version is wider at roughly 58 × 28 × 16.8 mm.

These files are especially convenient for a multicolor printer because the 3MF contains color information. The creator describes each topper as a one-piece print and prohibits resale or sharing of the digital file. Permission to sell physical prints is handled separately through the creator’s commercial-license arrangement, so do not assume that buying the model automatically grants commercial rights.

Choose Dulceideas for a simple flat print

The Dulceideas “Straw Topper Snoopy” package contains STL and 3MF files. The source recommends printing the model lying down without supports and using a filament change for a black-and-white result. This can be easier than a complex purge-heavy multicolor profile, especially on a single-extruder printer.

The related heart design is a smaller paid STL option. It works best as a decorative choice rather than the most technically documented file in the list, so inspect its opening diameter and scale in the slicer before committing to a full-color print.

Choose a pre-colored 3MF for fast multicolor setup

The Snoopy Clover, Peanut Dog and Elmos3D files focus on 3MF workflows. The AG Creations listing offers Standard and Stanley options and states that the file is already colored. The Etsy Peanut Dog file also includes two sizes, recommends a 0.2 mm layer height and suggests PLA or PETG. Elmos3D describes its topper as an 8–10 mm design with no or minimal supports depending on the slicer setup.

Small straw toppers are fast prints, but they expose calibration problems quickly. A clean first layer, controlled cooling and accurate extrusion matter more than high infill.

Measure the straw before slicing

“Standard” and “Stanley” are useful labels, but they are not universal engineering dimensions. Different cup generations, replacement straws and third-party lids can vary. Measure the outside diameter of the straw where the topper will sit.

1. Use a digital caliper and measure the straw at two or three points.
2. Check whether the straw is round, slightly oval or tapered.
3. Compare the measured diameter with the model’s stated opening.
4. Allow a small clearance instead of designing a force fit.
5. Print a short test ring first if the model is expensive or uses several colors.

For example, a measured 9.7 mm straw will usually be a better candidate for a 10 mm file than an 8.5 mm file. If the opening is too tight, do not force the topper onto the straw; scale only the hole or edit the model in CAD when the license permits modifications.

Accurate measurement is the simplest way to avoid a topper that falls off or cracks during installation. Measure first, then select the 8.5 mm or 10 mm version.

Recommended print settings for small straw toppers

Open every file in the slicer and inspect the first layers around the straw opening. Thin islands, unsupported color sections and an incorrectly oriented hole are easier to fix before printing than after the part has fused to a purge tower. For complex or damaged meshes, use the workflow in our guide to preparing 3D-print files for printing.

Black, white and accent colors make Snoopy-inspired designs ideal for multicolor systems. A pre-painted 3MF can save setup time, but it may also create more purging than a manual filament-change print.

Cleaning, drink contact and everyday use

A straw topper is not the same as a cup or drinking vessel, but it still sits close to a mouth and can collect condensation, dust and residue. Keep the printed part above the beverage, remove it before deep cleaning and replace it when the surface becomes damaged or difficult to clean.

Do not assume that ordinary PLA, PETG or resin is automatically suitable for repeated food contact. Prusa’s food-safe FDM guidance warns that layer lines can retain residue, while resin technical sheets commonly exclude food and drink contact. For a simple decorative topper, the safest practical approach is to prevent direct contact with the beverage, wash gently by hand and avoid putting a PLA topper in a hot dishwasher or on a hot-drink lid.

Small accessories can also be a choking hazard. Keep them away from young children and pets, and do not use a loosely fitting topper while walking, driving or exercising.

Copyright and commercial-use checks

Snoopy and Peanuts are protected character properties, and Starbucks branding is separately protected. The files in this list are third-party listings; inclusion does not mean that they are official, licensed or approved by Peanuts Worldwide or Starbucks.

• Do not redistribute an STL, 3MF or ZIP file unless the license explicitly permits it.
• Do not sell physical prints merely because the digital file was paid.
• Read the creator’s commercial-use terms and the marketplace license before selling.
• Avoid adding Starbucks logos or presenting a fan-made topper as official merchandise.
• For gifts and personal use, keep the original creator attribution where the license requires it.

FAQ

Bottom line

The strongest Snoopy cup STL choice depends on your straw size and printer. Start with the free 10 mm MakerWorld model for a quick test, choose the TeoRk 8.5 mm and 10 mm packages when precise sizing matters, or use a pre-painted 3MF when you want an easier multicolor workflow. Measure the straw, inspect the model in the slicer and read the license before printing or selling anything.
