Replacement Knob for Bretford Cart
thingiverse
Our school has an iPad cart equipped with handle end knobs that kept falling off, causing some to get lost. To solve this issue, I designed a replacement knob using Tinkercad (https://tinkercad.com/things/3MksBYwRnL6-ipad-cart-replacement-knob). If the fit is initially loose, applying a small piece of masking tape will tighten it for secure handling.
