Harley Davidson Sportster primary clutch/chain inspection plug

thingiverse

The threaded plugs on my primary cover were mismatched and battered, this being a nearly 40 year old bike. After researching extensively and discovering PETG would be suitable with the oil, I decided to create my own plugs. Currently, I have a few cap head allen bolts threaded into them for use with any flat tool to thread and unthread the plugs, but I might attempt some designs that allow a tool to be inserted like some of the stock plugs have. Also, I printed these in white because it was what I already had on my printer at the time, they'll become very dirty and oily, so you may want to print in black if you're concerned about that.
