Universal T-Slot Generator for Table Saws

Universal Non-Standard T-Slot Generator for Table Saws and Other Tools

The Problem

Many table saws, router tables and workshop machines use proprietary or non-standard T-slot profiles.

When the original runner breaks, gets lost or becomes worn, finding a replacement can be difficult, expensive, or simply impossible.

This was exactly the case with my Einhell TC-TS 2025/1 U miter gauge, where the original T-slot runner was no longer available as a spare part.

The Solution

Instead of reproducing a single fixed replacement, I designed a fully parametric generator capable of creating custom T-slot runners for non-standard guide rails.

The generated replacement shown in the photos was designed, printed and successfully tested on my Einhell TC-TS 2025/1 U table saw.

The printed runner slides smoothly, fits securely and restores the original functionality of the miter gauge.

Key Features

✅ Fully parametric design

✅ Adjustable length

✅ Adjustable profile dimensions

✅ Multiple fastening options

✅ Through-hole mounting

✅ Hex nut pocket mounting

✅ Countersunk screw mounting

✅ Suitable for replacement and custom projects

✅ Easy to print without supports

Tested Configuration

Machine:

Einhell TC-TS 2025/1 U

Application:

Replacement runner for original miter gauge

Status:

Printed, assembled and successfully tested

Print Settings Used

Material:

PLA+

Layer Height:

0.20 mm

Infill:

15%

Supports:

Not required

Print Time:

Approximately 22 minutes on a Bambu Lab A1

The design can easily be printed in PETG, ABS or other engineering materials if higher wear resistance is desired.

Parametric Generator Included

This project includes the OpenSCAD-based parametric generator used to create the replacement part.

The generator allows users to customize:

• Length
• Width
• Height
• Lip dimensions
• Fastener positions
• Fastener types
• Hole sizes

This makes it possible to adapt the design to many different non-standard T-slot systems found on workshop tools and machines.

Notes

This model was specifically tested on the Einhell TC-TS 2025/1 U, but it may also be useful for other table saws, router tables and workshop equipment that use non-standard guide rails.

Always verify dimensions before printing.

Help Build a Compatibility Library

This generator was created to solve the problem of non-standard T-slot systems.

If you adapt it to another machine:

✅ Upload your print profile

✅ Share your dimensions

✅ Mention the machine brand and model

Together we can build a growing compatibility library for table saws, router tables and workshop tools that use proprietary or hard-to-find T-slot runners.
