This is a redesign of phraust Y-Axis Motor Covers. Below is a list of modifications I made to that design for my own needs.
Alternate magnet type
Front and Rear V-Track brushes that will keep the v-track clear of debris.
Adjusted height to work with Y-Axis Stiffeners.
It uses 18 mm diameter magnets that are 5 mm thick you can buy at Lowes or Home Depot.
The brush is 1 inch brush strip from McMaster Carr. Same brush used for the Suckit Dust boot.
Print flat side to the bed.
