I work as an engineer and had a batch of plugs come in with faulty clamps. as the job was urgent I decided to mock this up and print a load of these instead (with fire retardant ABS filament) but if you're doing it for your own repair, ABS, PETG or PLA will be fine

i couldn't find any other files like this online so decided to make some and give back something (albeit small) to the community.

I've added the fusion files too if you want to make any edits.
