Organizer to put your Xcelite bits into an organized place on your workbench. Has a side cup for resting the Xcelite driver handle that you can find on this site.
Print with as low a filler setting as you can - model is hollow so I printed it with supports to make it come out very neat. All of the support will be internal, so nothing to clean up after the print.
