Ambrogio L60 Pulley
This is my attempt at a replacement pulley for Ambrogio L60 series robot lawn mowers. I spent some time getting the dimensions correct for a good belt-fit but have NOT had it in operation for a great length of time, so I have no idea of the robustness long-term.
You will need to make your own decision as to what filament to print this in for maximum strength. My prototype was printed in PLA and was fitting nicely. I have not put a PLA part under strain.
My guess would possibly be TPU as a final print but others would know better.
Please play with this and remix, adjust or beat it to death with a hammer. Totally up to you!
