The Leica Monovid 8×20 comes with a rear lens cover only, and no front cover. I found the intended pouch way too bulky and defeated the purpose of a small monocular, so I made these caps in order to be able to put it in any pocket without fearing for the lenses.
Print them flat in TPU.
I printed mine with TPU 95A, 0.4 nozzle, 0.2 layer height.
