Found this awesome STL for a Table Saw T-Track Adapter created by Michal@kopringo_696058 and really wanted to incorporate it into a Finger Jointing Jig I was designing. After using my calliper to measure the wide T-Track slot I decided to alter the original design to have zero wobble and I removed the front so that the Finger Joint Jig could sit flat against the T-Tack Adapter.
Since this is something I want to use on a table saw and with my router table, I will be printing this to be sturdy.
Printing Info: I printed flat on its side. You may want to adjust the STL to have it do the same. It will give you better adhesion to the buildplate and not rely too much on supports for stability.
Material: PLA
Print Temp: 202
Bed Temp: 55
Lines/Resolution: 0.2
Walls: 4
Infill: 40% or higher (either cubic or zig zag if you don't want to use as much material while maintaining strength)
Support: Tree (on Buildplate)
The author remixed this model.
Made front flat in order to make any mounted jig flush. Likewise, I slightly widened the t-track insert to sit snugly (while still being able to slide).
