Abstract: A drug delivery device assembly is provided, including an injector housing, a needle assembly, a drive assembly, and an alignment accessory. The injector housing may include a body with a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The needle assembly is at least partially disposed within the body and may include a syringe barrel containing a medicament and a needle or a cannula. The drive assembly is at least partially disposed within the body and operably coupled with the needle assembly to urge the medicament through the needle or cannula during an injection sequence. The needle or cannula is configured to pierce a patient's skin at an injection site. The alignment accessory includes an accessory body configured to be selectively coupled with the injector housing and an alignment aid configured to aid alignment of the accessory body with respect to the patient's skin at the injection site.
