Solektrik-9 v1.2

The SOLEKTRIK-9 is a blaster in a cyber-future where german trains run on time, no matter what. It was at first an unofficial development in 2396, by an engineering team finding itself in need of a short range sweeper for tight spaces, inbetween piping, and underneath engine blocks. The purpose was to clear out the smaller (colloquially and incorrectly named) "frost bugs".

The blocky and rugged mechanisms were easy to maintain and procure and the design spread quickly to other train engineers. The blaster uses commonly available 38mm caseless halfdarts. It was officially adopted and produced by the Megawerke in early 2398. Various improvements were made, including the standard light-up heat-piping and voltage meter.

Mechanically speaking, this is a mag-in-grip blaster that takes standard straight talon mags of any length. It fires darts with a fullsize 35mm solenoid that sports a self-regulating full-auto mechanism. There are no advanced electronics in here.

The darts are fed into a pair of micro flywheels (Cabanossi from Fetteworst are good here. The same wheels the HOLLÄNDER uses.) It uses 130er wheels, as normal. OoD Lokis are a good idea here, but any motor of that size will work well.

The blaster, as usual, is run with a 3S LiPo. You'll need to have your own 3S LiPo that can take at least 45A stall current. The compartment for that is above the barrel on the front, for overall balance. It locked with a pair of magnets, so you can just pull it off.

The blaster also has a built-in voltmeter up top, that is wired directly into the circuit. The main power switch is on the back of the blaster, below the solenoid.

Additionally it features two sling points, front and back. The blaster also has a separate rev-trigger that is attached to the front of the firing trigger, for that controllable dual-stage trigger feeling. It's basically the default for my flywheelers.

Known oddities: There is a chance that dart oddities can prevent the solenoid from fully returning (and thus stopping the blaster). When that happens just pull the solenoid pin back a tad until it clicks. I‘m still observing that one and how commonly it happens. It seems to be related to how much pressure the magazine is putting on the solenoid pin from below and how new the darts are. The strength of the lock spring could also have an effect.

All parts can be printed on a bed of 180mm edge length.

That will also let you know what hardware you'll need. Yes, there will be soldering and crimping.

Changelog

v1.0
- Initial Release

v1.1
- Changed the full-auto locking wedge to use a softer compliant mechanism instead. That also removes the need for that spring.
- Added an N-Strike stock point. That also puts a cage around the solenoid pin without impeding access to it.
- Changed the Nerf rails to picatinny rails. Feels like it's time.

v1.2
- Added tighter dart constraints to the flywheel cage, to increase firing accuracy a good bit.
- Added a bottom picatinny rail. Now you can attach a foregrip or underbarrel light or somesuch, for example.
