I liked the original design from aidilmazlan but needed something that would stay put and be a little less susceptible to being knocked over. Through holes were added to the base of the original model to accept M3.5 screws and added a base that can be filled with sand or whatever else you wish to add weight to the assembly.
The assembly was designed around using m3.5 x 9mm thread forming screws although the length could be anywhere between 6 - 10mm. I'll included the step file for the base in case you want to make a change to how the two pieces are attached togeather. The only reason for the m3.5 x 9mm screw is that I have thousands of them laying around.
The bottom of the weighted base has recesses for attaching .5" stick on rubber feet to keep it from sliding around.
I printed it at .2mm layer height with no supports.
The author remixed this model.
Added holes to the original model to accept m3.5 screws to mount the airbrush holder onto an included base that can hold sand, washer, sinkers or whatever desired to add weight to the assembly.
