Odd Built Machinery and Random Parts for Modeling/Plates, Blocks, and DC Motor Adapters

Hey...me again. AW! That is how I feel first off. Nothing is fitting so far. Outside of complications, the fixing will commence.

Bolts are not the issue here. I can purchase bolts. I am building, and I will list it as a part file below, a plate with an offset to fix a DC Motor Adapter on a Block for a Z_Axis part.

The Z_Axis has a block of 30.14mm * 60.19mm for the four holes that are threaded.

The Z_Axis has a motor adapter for the block. Neither of which are fitting. So, I will drill and drill to suit my needs.

The issue is with, I am thinking it is so far anyway, the plate that will be my offset to the different proportional holes and locations of the Block and Holder.

I have measured as well as possible and used an updated caliper for such measurements.

I believe there will need to be some type of burrowing in the metal for a set of four #10 (ID) - 3/16" (Width) * 1/2" (OD) circular Spacers. I bought some metal spacers.

My ideas was to attach the plate that is listed in the part below in between the block and motor holder.

Then, I drew a blank. What if my spacers are too wide at 1/2" and not able to be attached where they need to be located? I am here now.

I need to represent some measurements but also understand what exact parts can be used for these measurements before, maybe inlayed, and after the "plate." I am calling it plate because the end result will be a metal plate I cut and drill.

I was thinking of tapping the plate but I do not think it is needed...

@Ex Machina , I think out of everyone here, you may be able to make me understand things a bit clearer. If you have time, drop me some lines of ideas please.

Also, to anyone else here that reads my misunderstanding on placing a plate in between two pieces of metal, one a block and another an adapter, that will be used for a Z_Axis.

P.S. Blah. If it came already fabricated, yay. But, it has not been fabricated yet. This simple drawing will show you the plate at its earliest design phase.

Just to help the viewer here, the holes are so close. I am unable to provide adequate chamfers and/or inlays of bolt heads from bored holes. Please see the AD_PRT file above for my issue.

Also. Here is an update, the AD_PRT file is having a width of about 5mm or 4.81mm to be exact. I was thinking of getting a thicker piece of plate which would allow for this set of bored holes but currently in stock, the plate is about at 4.81mm as is...
 
Just an observation here...create each size hole pattern as their own steps in the Design Explorer. That will make sketches simpler. I'm not sure, but if Atom 3D has the Hole tool use that to create the holes, again a much simpler sketch since the Hole tool only uses Points to locate the holes.

Even without the hole tool having each size hole in its own sketch makes dimensioning more clear, less cluttered.

And make use of the horizontal and vertical constraints instead of multiple dimensions.

Gotcha. Okay. I will use the hole tool. I just needed the parts/holes to be aligned properly with a specific size. I did not know that the hole tool allowed for changing location of the hole(s).
 
Also, I can close this issue. I think I need to get a thicker plate, bore it, and not use chamfers. Dang it. The holes are just too close to risk the ripping when maneuvering the machine. Blah.
 
@HaroldL ,

Hey. Seth here. Okay and so, I think on Alibre Atom 3D when using the Hole Tool, it is not possible to handle the movements via the Dimension or Select Tool(s).

I have listed the part below for your viewing. If within the Sketching of the Hole Tool is where to handle this idea, I have not tried just yet. I was thinking I would go into a Plane on Sketching and then handle the movement of these pre-Holed parts in the block.

Okay and yeppers sir, I can alter the pre-determined holes with threading and counter bores in the Hole Tool Sketching. Yea boy!

Okay and blah to this day of DYI. To anyone, I am building an in between plate with counter bores to hide the heads of the bolts. This is the plate so far:

Please see the attachment...

Also, my bores come in contact with threading on the opposing side. What, if anything, is a plausible cure for this dilemma?

It is possible. Yes. I figured it out. Like you said, the nodes or points are what I can alter in the finality of the part to handle where the center of the hole tool is to be located.
 
To a machinists' eyes, I am trying to get some basic understanding of how to incorporate lack of space on XY Axes with Z_Axis ideas. If that makes sense, A-Okay. If not and if I need to explain more, please let me know.

m6 socket head bolts:
- m10 diameter of head
- m6 depth of head

m5 socket head bolts:
- m9 diameter of head
- m5 depth of head

My m6 head is gouging the threading of the m5 bolts on this part. I do not know how to manage a build of this "transfer" plate from one set of four screws to the second set of four screws.

Would two plates in this instance be a sound resolve?
 
Anyway, I am testing now. I am printing one with counter bored holes (threaded holes) and another with some type of idea... This "some type of idea" part is yet to be built. I need to try to configure things correctly before building and seeing it in 3D. Whelp, I feel a bit silly now but this is not exactly what I chose and I have to fix it...

My fix is to make the m6 and m5 bolts have an offset instead of being 100% even on all edges outside of their respective dimensional four hole sets.

So, without further ado, here is the build... Blah.

Hello. As some of you know, I am having a difficult time with this offset and build of the machine so far. Outside of practicing with actual models, my Alibre Atom3D build seems coherent but not when slicing it in a slicer for getting models that I can test.

Do you see why my model here in .stp format seems to be printing one side correctly while the flat base with holes on the Z_Plane creates a solid mass without holes?

Supports in a countersunk hole can look like a solid face. Look closely for fine circles where you expect the holes to be and use a pointed tool to pop them out.
 
Front and Center sir. Thank you. I saw it in the slice afterwards. It was the same color with the supports "mildly added" and probably by me without an update.

Seth

P.S. Supports were the cause.
 
Sometimes the most obvious thing gets by me. I have a working example now thanks to everyone who pitched in on this one. Thank you. I am learning more about the hole tool also.

Maneuvering it to and frow has become second nature now. So, and again, thank you.

Happy mother's day to any mothers out there and luckily for me, this is still a special day in the life of Seth (me). Now, to build this part in metal. Unlucky for me for now, the measurements on the drill press are standard and not metric.

I have been building in metric since the bolts are metric. M5 and M6 bolts on this effort. Off to color code the drill press I guess...
