Super Drum Zuis BK1s Neck

One of my favourite blaster is the BK1s. When I made the super drum, I was thinking what if there is a version I can use on it. So here is my attempt.

DO NOT use more than 3 drum springs as I found that it can stop the piston from returning. Even with 3 springs it can occasionally cause the piston not closing fully. Tried it with 2 drum springs and it was too weak and does not push the darts fast enough for it to load.

Might need to sand the mag catch indent slightly so that it will hold it in place. If the mag drops slightly, it will also cause a jam. Make sure to use a tiny bit of silicon spray on the mag itself. I used a brush to evenly spread out the lubricant so that the darts glides on it slightly smoother as I have encountered stuck darts.

I tried using the original darts that comes with the blaster and it's a bit oversized that causes frequent jams. Does not play well with worn darts. Best success I have right now are with Worker Bamboo gen2 HE. with just a couple of jams and may be due to worn out ones.

I used support blockers to stop supports from going all the way to the sides so that it's easier to remove them (See attached screen shot). Printed with 3 walls and 15% infill.

Let me know how it goes with yours and would love to hear some suggestions to improve this so that it works 100% of the time.
