Allen Key Handle

This model has built-in pauses to add your fallen keys before it prints over them completely surrounding your alleen keys. this handle improves ergonomics and makes using the fallen keys a lot nicer.FOR BEST RESULTS:do this to brand new fallen keys, sometimes old fallen keys are slightly bent which makes it harder to push in, resulting in frustration and scrapping the job potentiallyyou can do it on used Allen keys just understand the risks and be careful.Use glue. even for materials that don't usually need glue, you may want to use some so that the print maintains adhesion when pressing in your fallen keysI've made this model with some close tolerances so the keys don't raddle around inside the covers so a little bit of pressure is needed to seat the keys
