What did you 3D print today?

Siress Spider! It's a brass F1 barrel with a printed adapter bit. The tricky part was that the adapter is really thin, only 2 or 3 shells were possible to print in the thinnest spots. So after ensuring the fitment was perfect, i ended up epoxying the adapter onto the barrel. I haven't "fielded" it yet, but it's holding up well so far! The brass of the F1 barrel extends all the way through the adapter bit, so the cocker threads are really just epoxied onto the outside of the F1 barrel, so still really rigid with the brass "core" of the original barrel.

Siress pointed out your barrel, but it looks like the trick there is the printed cocker thread adapter. How is that working? I used to whittle those out very slowly on a lathe.

very nice. are they a bit longer for todays itty bitty balls?

Printed some automag barrel detents to send to some beta testers. Planning to add this to the mag parts thread at some point after testing.

Cool pump adapter.

Is that water pipe for a barrel? 😀 I hope you have video playing around with a 8ft barrel.

Pivoting version printed. It's much better than the sliding block version. I think some of my tolerances are off though, the spring isn't able to fully return the block. I think I'll re-print the block tomorrow, with a tad more clearance.

Yes, final version:

That’s neat, is it actually functional for more than a shot?

Once again not paintball related but hey, this is the very first print on printer number 5 (in 7 months). Hi, I’m Tony and I have a 3D printer addiction.
Funny thing is, the 4 other printers I purchased after my Ender 3 V2 total less than the retail cost of the one shown here! I will have to do a separate post to let my cat out of the bag.

This was printed on my FLSun Super Racer.
printed at 150% scale full default settings. 3h 56m. That would have been about 9 on the Ender.

That's actually a pretty cool idea. Way simpler than the dual valve hoopty Ion pump system. Lol

So, I did end up printing this, so I'll bring it in over to this thread. I'm calling it the P-MEK, or maybe the Pumpback (kinda looks like a humpback whale?), something like that. The idea being a mechanical mechanism to kiiiinda make the EMEK kiiiinda like a pump.

This is V1, and its... ok. It was supposed to work like the thumb lever pump on a thumper, and it kinda does. Pump stroke is a very short forward motion. But the force on the slider block is applied from the side, so when you pump it, the slider block cocks sideways a decent amount. I can still get the ball to drop into the slider block, and it actually does function! But I think I'll rework this into more of a "pivoting" block instead of a sliding block.

Also, it is possible to pump once and chamber a ball, and then pump a second time which puts one ball into the slider block in the "on deck" position. So you could then shoot two balls in a row. I think if I reverse the block so that the "at rest" position of the block is not directly over the feed hole, then I can fix that problem.

Anyway, just a silly side project.

game changer

Just because I can...........not because I should.....

Final version printing now.

Made a pair of shades for the landscaping lights that point straight into the bedroom window. They block just the window, and let the rain drain off the lens.

You copied my design!
