19mm T Track - 20 and 40cm long

19mm T Track I made for my CNC spoil board, it's printed on an angle so it's pretty strong. I haven't tested it long term yet though. I've printed mine with PETG so they're stronger, if you use PLA make sure to check the box to use your filament settings. 

If you're printing only 1 piece you need to change the speed to 50% so it has enough time to cool on each layer

The 40cm long version is split into two parts - I didn't glue mine together, but if you want your nut/bolt to run smoothly across the entire 40cm you might want to so the alignment is perfect. There is also a 20cm version as one part.

I also included a small test print so you can check that your hardware fits. I modelled it based on dimensions I found from aluminium t tracks, but it might not be exactly the same so it's worth checking first. The holes are for M3 screws.
