Buzz Bee Rapid Fire Tek Replacement Pison + Op-Rod

Witnessing a discontinued nerf-like blaster, especially the novelty that is the Rapid Fire Tek, fail mechanically - and watching the old plastic begin to oxidize and fail - is heartbreaking. If yours broke a tooth and you've been awaiting the day of a replacement, I'VE GOT YOU!!! :D

Alas, amidst the heartbreak, I have come to the rescue with God-given replacements! The good Lord inspired me to take out the trusty calipers and bust out these offerings. The challenge was not easy - I ran into continuous tolerancing and fitment issues, using old broken pieces to reverse engineer. Nonetheless, I have revived the thing successfully and with good power -and with my own custom shells, you get cheap ammo and a lifetime of action abuse with the peace-of-mind of knowing "I don't care if that Chinese company stopped making them - I can make my own now."

Thank you, God, for 3D printers. And calipers. And my incessant need to obsessively fix stuff.

SUPPORTS ARE NECESSARY in my tests, to make them dimensionally useful and accurate. YOU WILL STILL NEED THE ORIGINAL BUFFER, BUFFER SCREW, GASKET SEAL, CAPTIVE PIN, AND FIRING SPRING. Without these critical components the thing will not work right and eventually destroy itself. I advise lightly lubricating the gasket and the cylinder for longevity and smooth operation. No lubricants are necessary anywhere else.

I recommend using PETG/ABS and at least 80% infill, a raft for the oprod (if you're using old non-enclosed non heated-bed printers like what I've got) and maxing the infill as much as you can bear. 85% was the sweet spot for me.
It cycles and ejects about as smoothly and reliably as the original. The power is also pretty good - unsure if exactly up to the spec of the original but good enough with my shells plus half length darts to work reliably at tagging cans and vases across the room. Already put a couple hundred hearty cycles through it.

The design may change as I discover failures and difficulties with my design. What's there works for me and should work for you if your printer prints accurately to mine. Send in details and progress reports on your own makes and let me know how they work for you.

As well . . . I made this, tested it, and uploaded it for free because I love you. Don't make your own to sell! Pay it forward <3
