This gauge mount is made to fit an OEM basket for a 1982 Honda Express SR but should fit or be easily adjusted to fit most other wire baskets available. My sample pieces were printed in PETG on an Ultimaker S5 by my coworker (I can update with settings if anyone would like). The two halves of the mount are held together by a pair of M6 x 1.0 countersunk bolts (McMaster Carr 93395A357) with the gauge being held on by velcro (included with gauge).
