Small and simple CNC 3018 end stop mounts for cheap Amazon end stop set: https://www.amazon.co.uk/DollaTek-Mechanical-Endstop-Printer-Makerbot/dp/B07DK11STZ/ The printed part push on top the top of the axis support. Has cut outs for the component legs so you don't have to trim too much to fit flush. Two alignment lugs help hold it in place, use a bit of double sided tape to hold the PCB down or some small screws into the lugs if you wish. Part available in two orientations dependent on where you want to route your cables.

The slimness of the parts allows it to sit on the Y axis support and the bed to clear the top.
