Mostly 3D printed SPump

[The Great Equalizer]

You can also find this grip frame on much cheaper Brass Eagle Raptors (the old metal ones, not the plastic "Blade" that they rebranded "raptor" for a short period of time.)

This is absolutely fantastic. You're doing great work.

Any chance we can get access to the 3d files for this? I have a box of spyder parts and bodies and I bet could get a couple going with this.

Great build 👏
possible future spyder clone pumps 😏
Interesting..

It's just PLA, but that's plenty strong

[Sad King Billy]

people aren't even going to believe this was a spyder by the time you're done.

what material are you using for the grip frame?

[Numbskull]

Didn't realise this was posted here too! I remember seeing it on reddit and damn it's clean!

I really like your use of CAD and 3D printing here, not just in the parts you've designed for the function like the hammer and the sled, but that cutting jig too. I have one I am doing something similar with in terms of "half-blocking", and I am baffled at how easy and clean your idea made the cutting process. I'm very excited to see what you do next

[devilzcall]

I just whacked them real hard xD
The pins are 3mm, the holes are sized 3.2mm which should work on most machines and if not, you can drill them out.

That looks awesome. Any fitment/tolerance issues with the trigger pins?

I've got a very old Spyder Xtra that I use as a back-up and this has me intrigued. It's already "half-blocked" and has a reg, also has the lpc threads. It may be a perfect candidate for something like this 😁

Next Chapter: Custom plastic grip frame



I designed this frame with some inspiration from the ccm 86° grips but did want a slight backwards angle on them. The left design is 95° the Z-grips are 60°. No idea if those are actually usable, would probably need to angle the asa or just remove in favor of normal mounting screws.

The grips are also used to clamp a simple remote line on/off in place, similar to the previous one-piece design.

Here's the 95° frame, printed with all the internals in place:



I messed up the trigger-sear spacing slightly, so the sear doesn't reset independent from the trigger. That is perfectly fine for my purposes, but will be fixed before i make the files available.

It's from a rainmaker

[devilzcall]

That's cool! what marker is that from?

[devilzcall]

Thank you! I really need a nice metal file.
