Precision Heat-Set Insert Station Pro

Precision Heat-Set Insert Station for 3D Prints

Anyone deep into 3D printing knows the struggle: to create durable screw threads, you need to melt metal heat-set inserts into your plastic parts. Doing this by hand often leads to crooked threads and ruined parts.

This custom-built station solves that problem, turning a tricky task into a clean, professional, and repeatable process.

Key Features:

• Perfect Alignment: The soldering iron is secured in a stable guide along the vertical aluminum extrusion. This ensures the insert is pressed into the plastic perfectly vertical every single time.
• Adjustable Depth Control: Using the thumb screws on the back, you can set a precise depth stop. This prevents the insert from sinking too deep or damaging the opposite side of your part.
• Integrated Heat Protection: The base features a 100x100x3 mm aluminum plate. If a hot insert accidentally drops, it won't melt into the station's housing.
• Everything in Reach: The base includes a built-in drawer with 18 compartments. This allows you to store and organize various sizes of inserts (e.g., M2, M3, M4) right where you need them.

Why use it?

Instead of relying on a steady hand and guesswork, this station provides industrial-grade repeatability. It is the ultimate tool for makers looking to take the assembly quality of their 3D-printed projects to the next level.

Printing:

Print the handele.stl in 45° so it fits to the 250x250 print plate

Print Slider-front.stl, slider-back.stl (and stand-top.stl if you want the textured surface on the top) with Support all others don't need Support.
