3D Printing Guide

Coinfinity Stackers were designed to be 3D printed. They take a while to print and have magnets embedded inside. Learn how to 3D print your Coinfinity tubes, bins, lids, and bases after purchasing/acquiring the official STL models.

Printing Instructions

  1. Print tubes upright (standing vertically)
  2. Print caps upside down (top side down on the build plate)
  3. Add pause for magnet insertion (magnets optional)
  4. Face tubes forward so you can hide seams in the back
  5. No supports needed if oriented correctly
  6. Group prints: Place caps in the front and tubes in the back to track magnet polarity
  7. Insert magnets with correct polarity – see Magnets
  8. Check each model’s page for unique instructions
  9. Review the printing guides for each type below

Quality Tips

  • Use high-quality PLA or PETG
  • Clean your build plate before printing
  • Use an enclosure if printing PETG
  • Stainless steel nozzle NOT REQUIRED! even when printing magnet-embedded models, see Magnets

Printing an Army of Stackers

Want to print a large batch?

  • Split caps and tubes onto separate build plates
  • This saves time and helps with magnet polarity tracking
  • Organize rows consistently for large-volume production
