Dad dropped off the the prototype this afternoon:
And here it is fit to the sensor - I'm very happy with how well this fits for a first prototype.
Very happy with how well it fits together and seems I even got the radiuses of the beveled edges right!
It fits up nicely to the rail:
Planned changes for the next iteration:
- Enlarge mounting holes a bit to allow some wiggle room for the mounting bolts
- Enlarge hole for sensor nose as I had to file it out slightly in this proto.
- Reduce the thickness of the spacer plate. The piece is very solid and I think it will be better to reduce it back to approx 1.5mm so that the o-ring on the nose will sit a little bit lower in the air rail.
Dad will also print the next prototype with CF reinforced PETG which should be a suitable end material with sufficient heat resistance for this application. Printing in the target material will allow us to check for any dimensional variance with a different material (proto 1 is just PLA).
I think this should turn out well!
