Upgraded plunger head for Leedle Dynamics' amazing Anemone blaster. This hybrid design made of PLA and TPU replaces the plunger head from the original design. No need for elastic cord nor glue nor anything. 

This new plunger is 2mm longer than the original, so that there is just a little bit more clearance between the priming handle ring and the body of the gun. Without that the handle could collide with the body and break when the TPU bumper compresses (ask me how I know !)

Printing

Print the plunger core in PLA, with some sturdy settings (up the number of wall). 0.2mm layer height is fine. Orient the screw toward the top.

Print the plunger head out of TPU. Your standard settings will be fine, TPU is almost indestructible. I used some Polymaker 95A TPU, and it work perfectly. A softer TPU might give a softer landing to the plunger head when it reaches the end of the piston, but it remains to be tried (tell me in the comments if you try it with some softer / harder TPU). Orient the bumper font toward the top.

 

Proper orientation of both parts : 

Don't use any supports. It was designed with 3D printing in mind, and does not require any supports.

Parts should also come pre-oriented.

Assembly

Just remove the previous plunger, fix the new Plunger core instead, then screw the Plunger head on the Plunger core. I use some thick lithium grease, and it slides wonderfully !

Have fun !

Just tell me how this mod worked for you ! I'm super curious !
