For those of you that use tube style golf ball shag tubes to pickup balls in your golf simulator I recently released the design for two versions of a wall mounting bracket intended for 3D printing. The .stl files needed for 3D printing can be found here: https://www.thingiverse.com/thing:4706688 This design works for clear plastic style shag tubes and may be too small for the aluminum style tubes. If you have an aluminum style shag tube you may need to scale the size up a bit to get it to fit.
For those of you that pick up balls by bending over to pick them up, get a shag tube. You will be glad you did.
