Customer Reviews
Only issue that I found is that the files aren't made to fit a larger size gauge, after some adjusting in Blender, I got it to work just fine, but it wasn't a huge deal.
I had several dial calipers on hand, and all the necessary nuts, threaded inserts, etc., and found this while looking for a 3D printable option. I have 1/4" rod somewhere in the shop I can use, but got to find it.
The digital kit came with two different sizes of tramming bars, as well as the upright caliper holder. I printed the long bar and upright caliper holder, and plan to print the smaller bar soon.
I like the fact that I can place the dial caliper on the arm without using the upright holder. But I do plan to use the upright holder most of the time.
Tramming will come in a few days, but happy with the prints and the option to have what looks to be a quality solution from PWMCNC.
Printed in Sunlu PLA+, 4 Wall Loops for strength, 30% Gyroid Infill for the bar on a Bambu P1S. The upright was the same settings, but also include supports.
