Replacement Knob for Bretford Cart
thingiverse
We have an iPad cart for our school. There are end knobs on the handles, but they kept falling out A few got lost so I created this replacement. Instructions I made this in Tinkercadhttps://tinkercad.com/things/3MksBYwRnL6-ipad-cart-replacement-knob If the fit is a little loose, simply wrap a little masking tape and the fit will be so snug you won't be able to remove it.
