Star Wars Kenner Blaster Locking Knobs - recreate w/ centered lock

Have vintage 1978 Solo Blaster (with Black locks). Must of lost one lock long long time ago in a galaxy far far away. There was one model on Thingiverse but lock was not centered. I had an original so took measurements and created this.
Original had slight retention when installed, this part recreates that slightly larger lower part of lock so once inserted into door, has retention.
This part also locks a little tighter than my original, which after contemplation I liked better. Will see over time how it lasts.
Nubs on outer edge were a pain in the butt.
