Rubber Crank Dust Cap ?
 

Does such a thing exist or do I need to make them?

I am using early-80's Sugino GT cranks that are straight and in fact the mounting end of the crank where the dust cap goes sticks out a bit further than where the pedal mounts. Because of this I am bashing my ankles quite good when mounting or doing other odd maneuvers on the bike - for normal cadence pedaling I don't hit them. I noticed that modern cranks sweep out quite a bit more than these old ones and don't have a bulb where the mount to the bottom bracket (i.e. I never bash my ankles on my other bike)

Sounds like a job for Sugru moldable rubber: https://sugru.com/

duct tape ..

No worries. In the interim 14 years I've worn down my medial malleolus flush so it no longer hits the crank.

Thanks for sharing. I can see some bike related uses for this stuff, like maybe fixing brake lever hoods or a saddle tear. In the least, it would make a great gift for someone for whom I have no idea what to buy.

Excellent response!

Wow. That sticks out a bunch. I've never seen that. How about taking a file or grinder to them. Be sure to put a bolt on them first! I'm assuming the spindle has threaded ends of course. Maybe some gray caulk?

I am also looking for a dust cover for my crank.

This style (many brand/sources) bolt does both holding the crank arm on securely, and serving as a dust cap ..
