Dual Tank Spacer Wedge
« on: November 01, 2022, 03:20:59 PM »
I am working on a Dual Tank Benchrest rifle build, in the following thread....  https://www.gatewaytoairguns.org/GTA/index.php?topic=202750.0

The tanks and plenum are mounted to a "Y" shaped aluminum tank block at the front, but at the back I need a triangular spacer to fit between them, to hold them in position when I put a big hose clamp around them to make them rigid and prevent them from moving and stressing the threads, if bumped or dropped.... My son now has a 3D printer, and showed me how to use Tinkercad, so I designed this....



It's shown upside down, the plenum is on the top, but you get the idea.... Like a much larger version of this, with the wedge in between at the back....



What files do I need to send him, an .stl or what?....

Iíve got a plan so cunning you could put a tail on it and call it a weasel.

I got three tank spacer wedges for my Dual Tank Benchrest guns today from my son.... He used his 3D printer....





They are 100% infill, so solid as a rock, easily capable of taking the compression from a hose clamp, which is what will hold the tanks rigid at the back.... This was a perfect solution, I'm sold on 3D printing for certain jobs such as this....

I see your Son did a Triple wall. Good choice for that part.

It's 100% infill anyways.... Would the wall make any difference?.... He's pretty new at this, I don't know what choices his slicer program or printer software offer.... Maybe that is the default if you go for 100% fill?....

3 outer walls help to keep a part with in specs as designed.
A single wall, with a full infill can swell a part as the heat transfers.
For that part you have? You could do a few hollow areas to save filament and print time.
It would be just as strong and do the job just fine.

Your only applying a set amount of side force.

I'd do 3 hollow areas myself with 3 walls.
