The 3D Printed Star Insert is a precision accessory designed to create outstanding vertical resin pen blanks. This high-quality 3D printed piece fits directly into standard 3/4" PVC pipe, providing a stable centered channel that delivers consistent, professional results.

The star-shaped centering element keeps your resin pours perfectly aligned. The result is clean layered effects, dramatic swirls, beautiful color separations, and eye-catching mica shifts that make your finished pen blanks truly stand out.

Key Features:

  • Precise 3/4" PVC Compatibility: Engineered to fit snugly inside Schedule 40 3/4" PVC pipe while maintaining excellent resin flow.
  • Durable Construction: Printed with premium, resin-resistant filament that holds up to repeated casting sessions and cleans up easily.
  • Star Centering Design: Ensures perfect alignment during vertical pours for even walls and high-quality blanks every time.
  • Pressure Pot Rack Ready: Works seamlessly with our adjustable 2.5 gallon and 5 gallon pressure pot racks, creating a stable vertical casting setup that prevents tipping.
  • Reusable & Production-Ready: Built tough for both hobby makers and serious production runs.

This Star Insert turns simple PVC pipe into an effective vertical casting tube. It solves the common problems of off-center pours, shifting inserts, and uneven results, helping you produce better, more consistent resin pen blanks with less waste.

Compatibility & Suggested Uses

Designed specifically for use with our 2.5 Gallon Mold Rack System and 5 Gallon Mold Rack System. Ideal for single-color blanks, multi-stage pours, galaxy effects, and mica-shift patterns. Pair with our resin, mica powders, and pressure pot accessories for a complete vertical casting station.

How to Use

  1. Insert the 3D Printed Star Insert into your cut length of 3/4" PVC pipe.
  2. Secure the assembly vertically in one of our adjustable pressure pot racks.
  3. Pour resin down the centered channel and apply pressure as needed.
  4. Allow full cure, demold, and turn your finished blank.

Transform your blanks into showstoppers with these pro-level insights. Our upgraded V2 blanks boast finer shredded plastic for ultra-smooth turning and minimal chip-out— a game-changer over V1. Dial in sharp carbide or HSS tools, crank speeds to 2,000–3,000 RPM, and take feather-light cuts (0.005–0.015 inches) to dodge melting or gummy buildup. Wet-sand from 220 to 2,000 grit, zap pin-holes with thin CA glue, and crown it with Magic Juice polish for that mirror-finish glow. Dive deeper with our guides:
