Smeg Rangehood Pull-Out Replacement Ends

Whilst servicing this ~ 15 year old range-hood I noticed the plastic end caps/pieces of the pull-out shelf thingy (that's the technical term) were cracked and coming apart.

A short time later I had 3D printed replacement parts which I believe to be superior as they have an internal strengthening web and rib. 

Also found replacement parts online for “only” AUD $25 each !!

Printed in generic PETG.
