The Unofficial Instructables 2017 K'NEX Gun Contest!

Greetings, Instructables K'NEX Community! Now it's time for the Unofficial Instructables 2017 K'NEX Gun Contest! I am hosting this contest to hopefully stir up some creativity in the Instructables K'nex Community. There will be five winners, each of which will receive a place in my "Top Five New K'NEX Guns of 2017" collection. I will also post pictures of the winners' guns on this forum topic when the contest is over, and the winners will each receive a custom image "trophy" to put on their profile page if they wish. I will try to build as many of the entered guns as I can, and I will judge them by range, efficiency, accuracy, and innovation.

If you wish to enter in this contest, here are the rules:

1. The K'NEX gun that you wish to enter in the contest has to have been posted to Instructables.com from Jan. 1, 2017 and up. No older entries will be accepted. Also, it must be working. Test your gun out several times before posting it.

2. Your entry must be a fully documented Instructable, with pictures and full instructions, as well as information about the gun. A video would be preferred, but is not necessary. Multiple entries are allowed, but please take your time building your gun.

3. The contest is active from January 16th, 2017 - July 4th, 2017 (Updated). No entries will be accepted unless they meet these deadlines.

4. To enter, you must build a K'NEX gun in 2017 and post it to Instructables.com according to the guidelines listed above. Then, you must provide
a link to your instructable in the comments below. All entries will be posted above once accepted.

Now that the guidelines are clear, get out your K'NEX, awaken your imagination, and start building! I am looking forward to seeing, building, and testing the entries. Hopefully this contest will stir up some creativity in the Instructables K'NEX Community. If anyone has any questions or concerns regarding this contest, please PM me, or let me know in the comments below.

How many entries are there so far?

When do you expect to finish your gun? There is still time to enter it!

Probably going to run up right against the wire, as I'm facing some issues with component durability and weird friction issues. It won't be perfect probably, but I should be able to get it to at least last through 200 shots before the sling ends up breaking (currently using elastic paracord for that small section) and I should be able to have it break 50ft of range, even with the wildly sub-par projectiles I'm using. A few tradeoffs that would require a big overhaul to fix, but shouldn't be too much of an issue for normal users.

Okay, good luck!

Sadly, there are only two entries so far, and they are both made by the same person.

I guess I picked the right time to make a reappearance! ZipDart v.2 coming soon, that's what I'll enter

Awesome! I am really looking forward to it! It's great that this contest is getting so much attention.

The actual build is "super-top-secret" until posting it, but I've definitely gotten the core gun that I will submit. It is a bolt action, repeating railgun that gets upward of 100ft ranges flat (zero drop for a full 30ft, then gradual drop from there) with the ammo that fits in the magazine. Super psyched to get it working, but will definitely take my time before posting to work out every single kink I can.

Nice! Can you also make a video for it when you post it?

I'm still working on the thing, made a camera slide track with some of my other knex for making piano videos but am getting back to the gun. So far I'm having issues with the catch/trigger assembly as well as with finding a material for the slide that doesn't wear down too much from the movement and the shock but doesn't break the projectile. I may post a forum topic asking for help at this point.
