This is a ground skimmer "tripod" for getting low aspect wildlife photos.

I originally created these to fit on my older Anycubic Mega X machines, but this size version just barely fits in the Bambu.
Use 1 x 3/8"-16 1" length bolt to attach to your gimbal head.
30-50% infill seems sufficient for strength based on how much filament you're willing to use.
Support can help the 90 degree overhang for the bolt hole but I didn't use it.
