This is a tripod for the NERF Rival Prometheus, a 200 shot NERF blaster. It is meant to attach to a standard camera tripod, mine is a Revue 1633. Any tripod should work if it has a hole that will fit a ~22mm cylinder. This model uses 2 printed parts, 4 M3 screws, and 4 M3 nuts. I printed mine in PLA and a few of the clips snapped when i tried to put the gun in, but it still works pretty well. ABS or ASA might be a better idea to make it less brittle. (My PLA had also been sitting in a garage for 5 years and was quite brittle from that.)
