Sim Racing Rig caster support

My racing rig came with wheels but the screw was quite short and they would come lose too easily. I was worried about them shearing off so I created this as an alternative. To strengthen the model, this has the following setting: wall loops=4, top/bot layers=5, infil=gyroid, infill density=50%. Orientation is already set for best strength. The model pictured is working with just PLA, but will test with PLA-CF next if this one fails! Note that I made the screw hole the inner diameter of my screws and it threaded in VERY nicely, but there is a inset for a bolt! If people are interested I have a version that doesn't use the 8020 fitting, instead has holes so can just screw into the 8020.
