I have occasionally struggled to remove these caps with a screwdriver because of their awkward positioning on the kart and decided to create this for my own use to simplify our oil change strategy at the track. Hope you can use it and perhaps it will simply your life as well.
Be sure to use 100% infill so that they are durable and don't break on you.
