Guardrail Wire Bush - 4.0mm wire

I designed this bush to prevent the 4mm guard rail wire from wearing the aluminium stanchions on a boat.  They could however have other applications.  I could alter dimensions if there was any interest.

The are designed for 4.00 wire in a 9.50 hole x 22.50 long.

I printed in PETG.  I suspect PLA would be too brittle to allow the bush to snap over the wire.

I have attached files for a single bush or a set of six.
