In 2016, Hudson County (NJ) Community College (HCCC) deployed several wireless keyboards and mice with its iMac computers. Shortly after deployment, library staff found that each device’s required USB receiver (a.k.a. dongle) would disappear frequently. As a result, HCCC library staff developed and deployed 3D printed port covers to enclose these dongles. This, for a time, proved very successful in preventing the issue. This article will discuss the development of these port covers, their deployment, and what worked and did not work about the project.

在哈德逊县社区学院创建和部署USB端口盖

2016年，哈德逊县（NJ）社区学院（HCCC）在其iMac计算机上部署了多个无线键盘和鼠标。部署后不久，图书馆工作人员发现每个设备所需的USB接收器（也称为加密狗）会经常消失。结果，HCCC图书馆工作人员开发并部署了3D打印端口盖以封闭这些加密狗。一段时间以来，这被证明在防止该问题上非常成功。本文将讨论这些端口保护套的开发，它们的部署以及该项目的有效和无效方法。
