BALL POINT RETRACTABLE PEN

The pen parts print in about 30 minutes.  All 4 parts are in one STL file.  Also included is each part STL file and the handle for a 1.5mm Allen wrench.  There are two Clips, one plain and one with MORMON PEN text.  (Yes I am a Mormon, see my Temple models).  

I print these using PLA with the following settings:

0.40 nozzle, 0.25mm layer height, 60mm/sec speed, no support, no raft.  A built in support is removed with a chisel. 

Other Parts:  .024" (0.57mm) dia welding wire for making spring (10 turns, 3mm ID).  3mm x 6mm set screw.  TecUnite 2.75" pen refill (Amazon).  3400mm of 1.75 filament.  Total cash outlay about $0.70 per pen. 

Tools: Allen wrench 1.5mm.  3mm steel rod for making spring.  Wire cutter.  Hammer.  Chisel.  Tweezers.  Sand paper.  Drill motor, 2.5mm drill bit (70+mm long).

I have made 60 pens as of now and have 40 more in the works.  Mostly gifts for kids, grand kids, great grand kids and church folks.
