DeWalt DCR-020gb radio power cord tidy. Keeps the plug firmly attached to the radio unit when not in use. The printed part replaces the 2 standard lugs using the same screws.
Although the photo doesn't show it the plug push fully in.
Standard settings should be fine although I printed the following to be sure:
Printed in Prusament PETG
Nozzle - 0.4
Layer Height - 0.25
Infill - 20% Gyroid
Perimeters - 5
Printed face down no supports
