This is the page where public stls will be slowly released for the Chimera Nerf blaster.
Print settings for everything except the plunger head and the 100% infill parts are meant to be 20-30% hexagonal infill with .3mm layer heights.
NOTE FOR CURA USERS:
I have had SIGNIFICANT structural issues from 20% infill parts sliced in the Cura slicer. If you insist on using Cura, you will probably have to crank up the infill to at least 30% if you want parts to have any sort of strength. I HIGHLY reccomend slicing with either MatterControl or Slic3r, both of which, with a 20% hexagonal infill will produce MUCH stronger parts than Cura.
Parts "Plunger head mkalot" and "Actuator Mk3 Sealing Ring" should be printed at 100% infill and either .2mm or .1mm layer heights to ensure a perfect air seal between the layers.
NO PARTS REQUIRE SUPPORT MATERIAL, AS LONG AS YOU BRIDGING IS GOOD ENOUGH AND YOU PRINT IN THE CORRECT ORIENTATION.
Items that should be printed at 30% infill(Or greater depending on the strength of your infill pattern):
Priming Actuator
Turf Plunger Base
Trigger
Tlink knuckle front (x2)
Tlink knuckle rear (x2)
Superlink
Items that should be printed at 100% infill:
Catch Rev 4
Spreader Plate
NOTE ON 100% INFILL PARTS:
Contrary to common sense, .3mm layer heights are usually stronger than .2mm or .1mm. The main body parts can be printed at higher resolution if you're willing to take the greatly increased print time, but for critical 100% infill components, .3mm layers are optimal for high strength.

Update 9/10/2018 7:29AM:
RailGasm Barrel Shroud parts added. The new parts are "Barrel Shroud Front Half", Barrel Shroud Rear Half", and "pump grip rev 2 RailGasm"
Update 9/10/2018 7:19AM:
Plunger head updated, now printed in three seperate pieces to remove the need for supports and make sure the catch face is perfectly flat. The new parts are called "Turf Plunger Base Bottom", and "Turf Plunger Base Top"
Update 8/24/2018:
Plunger Head updated
Priming actuator updated to MK4. It is now a fully printed piece that cuts down on assembly time greatly. I recommend 30+% infill for the actuator.
Catch mount, catch spring mount, and stock cover updated to give .2" more compression room for people who were having issues with reliably compressing the Turf 20KG spring
NOTE: There are two fix shim pieces, "Stock cover fix shim", and "catch mount fix shim" Installing these pieces will allow you to use your old stock cover and catch mount prints, and still give you the extra clearance. The only part 100% necessary to reprint is t
