BUILD GUIDE CAN BE FOUND HERE:
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):
Turf Plunger Base
Tlink knuckle front (x2)
Tlink knuckle rear (x2)
Items that should be printed at 100% infill (And ideally 5+ perimeters):
Catch Rev 4
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.
RAW HARDWARE LIST:
-Hardware kits and production models have switched over to aluminum plunger tubes. The new PTs have a much better ID tolerance than the old poly tube (+/- .005" VS +/- .02") Which greatly helps reduce friction. Individual plunger head scaling to account for ID variance should be a thing of the past. New parts for the APT system include:
Plunger Head MKalot APT
Spreader Plate APT
Pizza Table APT
Catch Mount APT
Rear Tac Rail APT
Priming Actuator MK4 FULL LENGTH APT
Priming Actuator MK4 KATANA APT
-Handle has had some of it's edges smoothed out to make it a bit more comfy. The trigger slot has been widened to ease nutsert install and aid in trigger smoothness.
-Trigger and Trigger guide updated to fit in the widened slot.
-Added a flare to the Katana receiver's magwell on both the top and bottom.
-Added a flare to the Full length receiver.
-Cut a notch in the top of the Katana priming actuator to fix vacuum loading issues.
-"Chimera pivots all" added, which contains all 4 trigger pivots, and the catch pivot.
-Catch rev 4 updated. It is now recommended to print the catch with at least 5 perimeters, in addition to 100% infill. Printing in ABS or PETG would be ideal.
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"
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 the catch spring mount.
Back plate updated and spring centering stem added
Chimera lettering on "upper front rail mk5" updated so that it no longer cuts through the wall of the print sometimes.
Update 8/21/2018: Plunger head updated
Update 8/17/2018: Spring change system deleted, the blaster now uses aftermarket LongShot springs. A few other things also tweaked.
BIG UPDATE 8/8/2018 Many parts updated to the latest version
-Actuator MK3 Sealing Ring: Better seal and fit on the alloy tube
-Actuator MK3 Top: Better tolerances on the M3 Nut Slots.
-Actuator Sealing Nub KATANA (Sealing nubs are now specific to magwells due to length restrictions with the 4 inch prime and reliably chambering Elite darts.)
-Actuator Sealing Nub FULL LENGTH
-Lower Receiver KATANA (Tolerances adjusted, and a small groove added to fix the issue of the mag follower catching on the sides of the magwell. Support structure for the dovetail removed.)
-Mag Release KATANA (Mag catch made slightly smaller as it would occasionally catch on the follower spring)
-Tool-less Spring Change Cap (Way more comfortable handle on the Cam Lock)
-Plunger Base (Side cutouts removed, switched from using a nutsert to mount in favor of a through bolt and Nylock. Center diameter increased slightly to all for K14 springs)
-Plunger Head mkalot (Seal close to perfected at this point.)
-Catch spring mount (Nub made smaller to fit better on the extension spring)
-Stock Cover (Cutouts added so the cover doesn't foul on the Catch Pivot's Nylock.)
-Back Plate (Now is attached to the Stock Cover separately from the Stock Pad.)
Please note that even with this huge number of updates you can still get away with older parts with slight modification. The most crucial parts to re-print are the Plunger Base, Plunger Head mkalot, All the Priming Actuator pieces, the Back Plate, and the Katana Mag Release.
Update: 7/25/18 Plunger head updated, Plunger Base updated, Actuator Sealing ring and sealing nub updated.
Update: 6/25/18 Main body components added
Update: 7/14/18 All components added, plunger head still subject to change
Update: 7/15/18 Separated 100% infill items added, a few items I forgot added.
Update: 7/20/18 Plunger head updated, slightly better seal and no longer requires support material.
