Amana CNC Bit Holder

Amana CNC Bit Holder

I purchased a set of Amana CNC bits that came in a wooden box. However, when transporting them to the shop, they would fall out in my bag. To solve this, I designed an insert to make the box work as a carrying case. The insert includes a pen spring mechanism that keeps the base stable during storage and allows it to pivot out for easy access to the bits. I also can hold more bits now which is great!

The JK generation of Jeep Wrangler did not come with a backup camera. The aftermarket mounts you buy on amazon and eBay has a bracket that goes behind the spare and has the camera protruding up and out above the top 2 lugs. The angle is horrible and the camera vibrates while moving due to the awful design.

For a while, I just drilled a whole in the center hub and mounted a camera through that but if you take the spare off you have to know to disconnect the camera, then pop the hub cap off and its a pain (especially if someone else is going to work on your car).

I designed this to mimic the new JL series that has the camera poking through the center hub so the wheel can come on and off without interfering with the camera. It is printed in PETG so I am hoping it will hold up a few years. Going to test it in some extreme weather for a few weeks before posting the stl.

I'm about to design something and I'm stuck on a part of it that I don't even know how to search for this specific circumstance...can anyone assist?

Ideally if anyone can think of something that might have this type of scenario in the design process, maybe I can find someone on youtube that makes something in Fusion that I can see how to make this work on my own design.

This isn't what i'm designing, but what I'm trying to do would just over-complicate the explanation, so for simplicity sake, just pretend like I'm doing this dumb thing. In this example, I'm trying to make a holder that snaps onto a pen, and then on the back of these holder will be a circular piece about the proportions of a hockey puck, so that I could put a drop of glue on the back of this puck and stick it to the wall.

I know how to design the holder piece that the pen will snap into, and I know how to design the little puck piece for the back, but when you bring those 2 pieces together (as shown in the top view of my drawing) you will see that they clearly only meet at a very thin strip down the middle, so the green area of the top view shows where more material must be printed to securely attach these 2 things, and I am not really sure how to fill in these gaps in Fusion.

Is there any kind of algorithmic way that Fusion can look at it and determine how to join these pieces together with the proper amount of "support fill" (but not actual supports, i'm trying to do like a solid appearance, so it looks like 1 solid piece, kind of how it would look if it were injection molded).

If there is a name for this, or some type of common design that might implement this type of thing that I can look up, I would appreciate any help.

Thanks!

"venturi washer" openscad code included

I lost it during cleaning the paint gun.

Bought a second paint gun to finish the job and recognized why the first one didn't take color anymore, the washer was missing!

No way to buy a replacement! So i made this tiny openscad file to print my own.

https://www.printables.com/model/934438-paint-gun-venturi-washer

dia_outside = 33.2;

dia_inside = 21.2;

wallsize = 1.2;

dia_holes = 3.0;

thickness = 1.1;

holes = 20;

height = 2.8;

$fn=120;

union(){

`difference(){` `cylinder(d = dia_inside + wallsize*2, h = height);` `cylinder(d = dia_inside, h = height );` `}` `difference(){` `cylinder(d = dia_outside, h = thickness);` `cylinder(d = dia_inside, h = thickness);` `d = dia_inside/2 + (dia_outside/2 - dia_inside/2 + wallsize)/2;` `for(a = [0: 360/holes : 360-360/holes])` `rotate(a)` `translate([d,0,0])` `cylinder(d = dia_holes, h = thickness);` `}` 

}
