Travel Weight for Star Adventurer

Travel weight for my Star Adventurer. It also doubles as a tripod weight when used with a length of cord or neck strap from an ID card etc. I made two sizes of weight to give some options but in use I'll probably carry two of the smaller ones, and I opted for a swivel lid for convenience. The weights are 90mm in diameter and the smaller one is 50mm in height and the larger one approx. 85mm. The idea is that these can be loaded with materials on site, e.g. sand, gravel, coins etc. saving weight w
