Handler was designed to held tight all long adapters and bit in hex size.
Intention was to not replace bit to another one. Of cource it is possible to change, but you will need use some little force to remove from handler.
Instead of chuck you can use long bit, extension bit or even chamfer bit.
Printed with 25% infill and 3 perimeters should be strong enought.
