Dawn PRO MAX

Update Instructions
1. Removed the magnet slot on the Pro version's pull-bolt decorative cover; testing shows it latches directly and magnets are unnecessary
2. Modified the T-joint, integrating it with the receiver to prevent breakage; removed the O-ring from the T-joint's inner tube to reduce assembly difficulty; reduced the inner diameter of the T-joint's rear end, testing confirms no performance impact
3. Modified the nozzle push rod diameter and nozzle O-ring specifications (12mm outer diameter, 2.4mm wire diameter); changed to an adjustable mode, from double O-rings to a single O-ring; modified hardware specifications (M3*3*5 heat-set inserts x2, M3*25 cap head screws x2) to secure the base and nozzle; testing confirms the O-ring does not jam the cylinder and does not affect performance
4. Modified the cylinder, chamfered the dart chambers, and deepened the rear of the dart chambers; testing avoids jamming during rapid priming; soft dart specifications are now within 60mm length, standard short darts are recommended
5. Modified the release block, shifted the ramp forward to prevent non-rebound issues
 

If you have printed models with issues, you can directly print the first configuration file and replace the existing parts

For hardware purchased before June 29, print the original configuration file; you can also print the new configuration file, but the hardware has slight changes (T-joint and nozzle hardware, as explained above)
For hardware purchased after June 29, directly print the corresponding new configuration

The instruction manual is currently the pre-update version, a new manual is being produced

Dawn Breaker is a Lucifer skin mod I made a year ago; although it had a good appearance, its performance was slightly lacking
This upgrade was originally intended to expand the cylinder to improve performance
However, it ended up being almost completely redrawn
Not only was the cylinder expanded from the original 67cc to 94cc
but capacity was also increased from 6 rounds to 8 rounds

The overall appearance has been redesigned with a strong sci-fi aesthetic

Compared to the original Dawn Breaker, it is noticeably bulkier

making its weight comparable to fitness equipment

This time, ample hardware is used (Hardware produced by Xiaojie Modian)

The gantry nozzle link still uses a 4mm stainless steel plate, but this time the dimensions have been revised, and a pull-bolt slot has been added
Stainless steel cut pieces have been added to the gantry to enhance durability
The pull handle is a 4mm stainless steel cut piece, completely eliminating the risk of breakage
Due to increased capacity and enlarged dart drum, the trigger linkage has been changed to a custom-shaped part, cut from a 2mm stainless steel plate
10 bearings have been added to the gantry slide block to fix the gap between printed parts, and the slide block grip is secured by two guide rails to prevent friction between printed parts
Two 2mm stainless steel plates have been added to the stock for structural reasons to increase strength; the central pull rod and shoulder rest bracket are both stainless steel cut pieces
The aluminum tube is a custom externally threaded aluminum tube; the T-joint's main upgrade this time is using threads to secure the aluminum tube, with an internal rubber seal
Both the cylinder and aluminum tube have undergone oxidation treatment, maximizing aesthetic appeal
The connection for the middle part of the launcher has been changed from long screws to an internally threaded aluminum tube, secured by screws at both ends
Overall, there are many custom parts, and most are made of stainless steel, so this hardware kit is quite substantial
 

There are three forms of play this time

The first form is a bullpup pump-action revolver shotgun, similar to the Dawn Breaker Mini, hence named Dawn Breaker Pro; compared to the Dawn Breaker Mini, it's significantly larger, with a length of 65 cm and weighing 3.5 catties (1.75 kg); in this state, it can hold 16 soft darts; as is well known, only by firing two shots at once can it be called a true shotgun

The second form is a pump-action revolver rifle, now equipped with a 12-axis modular bearing tube and sight (this sight is a four-reticle lens shade); with the stock attached, the shooting experience is more stable and accurate, and the length increases to 88 cm; this form is Dawn Breaker Pro+

The third form is a bolt-action revolver heavy sniper rifle; the front handguard is lengthened, the bearing tube is increased to 24 axes, the slide block grip is replaced with a fixed grip, the pull handle is changed to a rear pull, and a dedicated sniper sight (this sight is a four-reticle lens shade) is mounted; this completes the heavy sniper form of Dawn Breaker, with a length of 113 cm and an overall weight of 6 catties (3 kg); this form is Dawn Breaker Pro Max

Regarding printing, printers below the 256 platform are not currently supported; I will adapt it for 180 platform printers later
