Slider Mounting Bracket

This is part of a modification to motorize a slider module.I designed it to attach the Arduino control unit by using velcro tape. Similar modules can be purchased on Ebay, Amazon, etc. The module is available under different brands and I asume the only difference is the label. In my case the manufacturer is Tarion and the type is TR-V500. This unit does contain grub screws as shown on the pictures to attach the rails to the end plates. I simply replaced the existing ones against longer ones to mount the bracket to the end plate of the module by using butterfly nuts. Because I was not sure if this is strong enough two additional bores for countersuk head bolts which hasn´t been used.
