Power Plant Junior and Spaceship 50M

[Remy Yeldrem]

So I bought a Harley Benton Spaceship 50M, I've never really used a pedalboard before and I didn't think there was enough room to fit my Power Plant Junior underneath. So I stuck a bit of velcro on the bottom of the Power Plant Junior, it seems a bit loose though. So, my question is:
How do I go about securing it, properly?

Adding zip ties to the velcro can help secure heavier things, assuming the placement allows for it. The velcro helps keep it quietly in place, and the zip ties keep it from falling off when you move the whole the thing around.
