3D Printed Retractable Click Pen

One day while I was fidgeting with my pen I somehow managed to break it, so I went to look for a retractable pen to 3D print but couldn't find one so I decided to design one my self. Introducing, the 3D Printed Retractable Click Pen! ( very generic name i know) I designed this pen to be printed in .1mm layer height on a .4mm nozzle. Q&A“What pen inserts does this use?”I designed this pen to work with Pilot G2 07 inserts. “My parts aren't sliding in”Tolerances on the pen are pretty tight but my settings should work. “My Pen keeps on jamming”Note that the pen needs to be break in to function reliably( This is also my first time making a functional part like this so feedback is appreciated. )
