T19 Build Guide - Part 1 - MASTER POST and 3D Printed Parts

This will be a many-part series of posts covering the build process of the T19 blaster in standard "Model 101" trim:




Anyways, a good place to start is with all the non-COTS parts that are supplied as models for you to manufacture. I assume that you are going to FDM print these as they are designed for.


Tools:
  • FDM 3D printer
  • Computer with slicer
Parts/Materials:
  • Filament
The models are available here from the DZ Industries Google Drive: https://drive.google.com/open?id=17zi6XGi_Rp5biofmGVj_0ZyBb71Q0HPR

Some general notes: NO supports. Assumptions are 0.2mm layer height unless noted otherwise, and 0.4mm nozzle/~0.45mm extrusion width (you figure out the conversions if you run atypical nozzle sizes). You should be able to run all of these parts with a 170x170x170 (ish) build volume. It is strongly recommended to use PETG, or ABS, or other materials with reasonable mechanical properties, passable toughness, and serviceability at ambient temperatures that may be encountered in combat conditions. I do not test and cannot support PLA. If you use PLA and it warps or cracks, that's your problem. Machine accuracy, extrusion settings, etc. are also your responsibility. I am not responsible for incorrectly printed parts and I am not your printer technician.

Crank Pin Bushing

Bolt

Mesh Filename: T19_Bolt.stl

Print Parameters:
* Standard - 3 perimeters, 6 tops/bottoms, 30% hex, aligned
* Lightened (Recommended) - 2 perims, 4 tops/bottoms, 20% hex, aligned

Orientation: Top/bottom side on bed

Notes: Upcoming "Class 4" bolt kit will be destroked and further lightened for better high ROF operation.

Stock Buttplate

Mesh Filename: T19_StockButtplate.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Flat side on bed
Drive Spacer

Mesh Filename: T19_DriveSpacer.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Bottom (flat) side on bed
Drive Cover (Top Cover)

Mesh Filename: T19_DriveCover.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Top (flat) side on bed
Lower Drive Housing

Mesh Filename: T19_DriveHousing.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Top (flat) side on bed
Breech Housing

Mesh Filename: T19_Breech_Rev2_fixed.obj

Print Parameters: 3+ perims, 6+ tops/bottoms, 30%+ hex, aligned

Orientation: Top on bed


Hy-Con Gamma Major/Main

Mesh Filename: Hy-Con-GammaMajor_Main_Rev2.1.stl

Print Parameters: 4+ perims, 8+ tops/bottoms, 100% infill (for the love of the friction-ballistic gods, please heed this and leave the "100% infill not any stronger" armchair design BS at the door), aligned.

Orientation: Top (flat surface) on bed

Notes: Skookum part or die
Hy-Con Gamma Major/Cover

Mesh Filename: Hy-Con-GammaMajor_Cover.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned.

Orientation: Bottom (flat surface) on bed


Hy-Con Gen3 Flywheels

Mesh Filename: ./Hy-Con-Gen3-Wheels/Hy-Con-Gen3-[dimension]mm.stl

Print Parameters:
* Standard - 3 perimeters, 4 bottoms, 3 tops, 20% hex, random start point.
* Optional - 0.1mm layer height with 8 bottoms, 6 tops.


Orientation: Flat end on bed.

Notes: A range of flywheel models of different gap settings are supplied to suit tuning preferences/desired velocity/dart damage. 9.5mm is the default for higher velocity. 10mm is a good starting point for FDL-like performance, perhaps. Two copies required. These are high-speed rotating parts, so pay particular attention to machine accuracy before running this job, and use random seam position. Print parameters as specified are important to produce OEM-equivalent moment of inertia and thus compatibility with default assumptions of drive dynamics in the Core firmware. Make sure your machine's part cooling system works properly to get an accurate and smooth surface on the overhanging groove flank as this is a somewhat demanding overhang print.

Motor Controller Covers

Mesh Filename: T19_ControllerCover.stl

Print Parameters: 3 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Outside surface on bed

Notes: Two required, a right and a left. Only one model supplied. Reflect one copy about an axis when slicing.
Stock Body

Mesh Filename: T19_Stock2.stl, T19_Stock_Charge2.stl

Print Parameters: 4 perims, 6 tops/bottoms, 30% hex, aligned

Orientation: Back end on bed

Notes: There are two versions of this part. One has the provision for a DE-9 connector for internal charging of the battery. One does not. If you use lipos, internal charging is not advised, so I recommend the portless version. Also, this part contains bridging extrusions and prints with a 0.2mm membrane over the stock tube hole to aid this.


Stock Base

Mesh Filename: T19_StockBase2.stl

Print Parameters: 5 perims, 8 tops/bottoms, 40% hex, aligned

Orientation: Back (flat) surface on bed


Flash Hider



Mesh Filename: T19_FlashHider2.stl

Print Parameters: 5 perimeters, 8+ tops/bottoms, 100% infill, aligned

Orientation: Back (flat) surface on bed

Notes: Perhaps you can tree why this "seemingly inconsequential" part's updated version is beefy, and why slicing it robustly is recommended - it's on the very front of your blaster, and is the first part to get into the carnage.






Here's what your full set of prints should look like:


Next steps will be prepping and cleaning up these prints, introducing the "vitamins", and building subassemblies.

  1. glad you're back at it. I printed off most of the parts here not too long ago in hopes you'd post a build guide. I need to work on the black nature of my blaster at the moment.
