What we can make

Custom Caps and Plugs (zaglushki)

Fast custom caps and plugs for holes, tubes, and connectors where standard catalog parts do not fit correctly.

What we can print

  • Threaded and press-fit caps
  • Tube end plugs
  • Dust covers for connectors/ports
  • Custom shape hole plugs

Typical use cases

Good for automotive trim holes, appliance covers, electronics ports, and workshop gear where dimensions vary by model.

For regular use parts, we can suggest PETG or ABS-based options for better durability.

How to request this part

  1. Send opening dimensions (inner/outer, depth, thread info if any).
  2. Add photos and where the part will be used.
  3. We prepare a printable model and confirm quote.

Why this works well for 3D printing

These parts are usually ideal for short runs, repairs, fitment fixes, and one-off custom work where off-the-shelf options do not exist or do not fit well.

  • Fast to iterate when the first version needs a small adjustment
  • Easy to match measurements from a broken sample, sketch, or photo set
  • Possible to split large models, add connectors, and combine printing with finishing

What helps us quote faster

The best starting point is a few clear photos, rough dimensions, and one sentence about where the part will be used.

  • Add load, heat, weather, or fit requirements if the part is functional
  • Tell us whether appearance or strength matters more
  • If you need several units, mention the target quantity because that can change the best production approach

Materials, finish, and next step

For utility parts we often suggest filament materials, while resin or finishing can make more sense for small visual details, display models, and smoother surfaces. For larger repeat orders, we can also prepare a free prototype before production.

Send your references through the quote form or the support form. Writing to support@best3d.eu is still an option too.
