PH Adjustment Caddy

Just a convenient little doo dad to bring all tools and products together for managing hydroponic reservoirs. Holds 2 bottles, 5 syringes, a tablet and 1 generic TDS meter. I still need to design another saddle to hold my Milwaukee PH pen as it has a peculiar shape and will require it's own space. I should have that designed and printed in the next few days. The syringe sizes are

3ml
12ml
20ml
35ml
60ml

The handle requires an M3 screw to assemble. I used a countersunk M3 x 6mm.
