This is the original base from the Captain's Lantern by Bugman_140. This is a bracket for mounting the lantern to the wall using screws/zip ties. Use the same settings as you use for the Captain's Lantern as this is an exact replacement.
My use case, zip tie to a four-post tent. This is a drop-in replacement for the original base. I recommend a spot of glue or tack for holding the lantern in place.

The author remixed this model.
Modified the base to allow for wall-mount or zip-tie mount.
