Adapters designed to be compatible with the Cen-Tec Quick connect system.
I was asked to add support for Cen-Tec quick connect system, however I don't have the adapter, so cant test these.
If you are interested in these models, can I suggest you first try the centec-test-print.stl model first which is a test print. If you could provide feedback on the fit, and any suggested changes that would be appreciated.
Thanks to @landrypm_1136114 for your help in testing the model.
