Digital Miter Stop

This is a 3D printed digital miter stop that allows for extremely small cuts close to the blade without sacrificing accuracy. 

Based on this design by @HookedonWood, this model is designed to be 3D printed for easy assembly, hidden cables, and cheaper parts.  Here it is in action:

Parts required (and links to my purchases, but most of these are standard sizes so shop around):

Miter Stop Parts:

• 3 tiny zip ties
• miter slot nut and knob - I already had one of these.
• miter slot bar - I ordered this one.
• 25mm M6 bolt to hold the base to the miter bar
• 20mm M6 bolt to hold the stop to the miter bar
• 25-30mm M3 to hold the sensor to the base (and nut)
• 400mm miter bar 
• M503 Magnetic Scale or similar with enough magnetic tape for your workbench (I purchased this; double the price to get one with a shorter cord)

Relevant parts (size to your specific bench needs):

• regular T-Track (I used this [china] and this [amazon] in my workbench)
• 45 mm miter track (you can also use 30mm, but with 45mm spacing will ‘just work’).  I purchased this one.
• 1/8" mdf to lift T-Track to equal height.

Printed with PETG using a 0.6 nozzle at 0.4 quality and 10% infill.

Assembly:

1. Print enough t-track inserts to fill the t-track, 1x base, and 1x stop.
2. Install the Miter bar and t-track
   
3. slide inserts into the t-track and the magnetic strip will slide on top
   
4. Assemble the miter base.  You will need to put the zip ties through the hole before pushing the 503 unit fully in.  Then wrap the cable and pull it tight.  Put the M3 screws in to hold the sensor in place (upper left of the below picture)
   
5. Install the M6 screws to hold the miter bars in place
   
6. Follow the instructions for your unit to set the 0, direction, metric/imperial, etc.
