This is a simple mount and harness for the PCT type of wire connector. These little things can be difficult to stick down with VHB and the rest on their own.
The uploaded Fusion file includes some simple adjustments to the base for changing length and hole centres.
There are some small integrated support in the base slot rebate to aid bridging. These also have a parametric adjustment to the centres if extending the harness.
No other supports are required if printed in the published orientation.
The author marked this model as their own original creation.
