I modelled up a support plate to hold the AC to DC Convertor Box that goes with the Emblaser Core. Originally I used a strip of 50mm/2" Velcro on the back of my Emblaser Core to hold the AC to DC Convertor Box, but the box was too heavy for the velcro and it would intermittently peel off and fall. So I modelled up a backing plate which bolts on to the exisiting holes that are in place on the Emblaser Core.
