NMR Depth Gauge

This is an 3D printable NMR depth gauge for Varian style spinner. We use this gauge with our R2D2 magnet attached to Varian Inova NMR spectrometer.

Ampule depth (measured from spinner bottom) here is 124 mm. The model can be easily changed to accommodate different depth. The hole indicates position of the coil in 5 mm probe, and its centerline.
