I have my Lakeside Focuser boxes around the outside of my metal pier held on by wrapping a wide piece of velcro around them. The problem is they do move a bit now and again. So I decided to design and build some Lakeside Focuser control box holders. I added two slots in the back to still take the velcro straps, but you could drill holes in the brackets if you wanted to hang them somewhere else.
I made the first one slightly too wide, so decided to remove 2mm off of the width for the second box holder. Now the Lakeside Focusers will remain in place and also remain safe.
