Yep - same pen new cap.
I figured out the problem too.
The drill bit I used to create the largest hole had a very flat secondary relief, so it was very hard to push the bit into the material to drill, creating lots of heat and warping the plastic. I hit the bit on my bench grinder and created a steeper secondary relief and it cut through like butter. Perfectly straight pen to cap mesh up too. The pens went off in the post this morning.![]()
