Summary

Made a very basic Heltec V4 board holder for a waterproof enclosure. holder has spring clips to hold board in place and there is a version which covers the antenna connector in order to keep it firmly in place (Shown in photos). Clips are slightly delicate and should be printed 100% infill.

I used automotive grade double stick tape to adhere it to the inside of my enclosure but there is room beneath the board if you wanted to drill and use hardware.

this design should also work for the V3 but I have not tested it to prove it. If you do use it for a V3 chime in in the comments to verify.
