This was more or less just a exercise for me to get a little practice. I know the FSP motor coupler is pretty cheap and at this point made out of better material then what I'm capable of printing from home at this time.

With that being said the type of materials for 3d printers will only continue to expand as time goes on along with the rest of the technology.

Anyway on to my exercise. My goal was to create a accurate CAD file for the 285753 Motor Coupling using what skills I have learned so far and share it with the world for free.

The .stl CAD fie can be download here.

I may print one this weekend just to see how it looks side by side with the FSP part.

Do you think it looks like anything like the FSP motor coupler?

Thanks deekin!

Not sure what version you seen as I just made a small change to the CAD file a few minutes ago. One part of it just did not look right to me and I finally figured out why this morning.

Anyway uploaded the change to thingiverse and now I think it looks exactly like the FSP one. :)

I spent a good part of my evening on this part. Between getting all the measurement from the original part with my calipers. Figuring some angles and radius. Writing down the dimensions on my hand drawn sketches and then finally getting to work in my CAD program. I would guess about 4-5 hours, but I'm still very new to all this.

From what I have seen in the CAD forums I visit a pro could have probably done it in a half hour or less. I learned a lot from it though and it would probably take me less then half the time if I was to do this same part again.

Well that didn't take long. About a week after I posted the .stl file on thingiverse at least one person that I know of besides me has already printed it.

Here is some feedback they left about the part.

Attempting to print now. I am using high impact abs with a 100% infill I did turn it upside down on print bed and used a raft to print on. I will post more if it works for me. I may try and print in nylon as well for it should last longer.

It printed very well exact copy of the original part I hope it is strong enough I printed the center bushing in pla at 75% infill I haven't had a chance to install yet thanks for the design

I attempted to print the part myself last weekend, but part way through the laptop I had running the printer decide to reboot itself thus stopping the printer dead in it's tracks.

I must say I do enjoy the CAD part of things so much more then the actually 3d printing of things so far. The 3d printing part would be more enjoyable for me if it didn't take so darn long to print everything. Maybe I will get a faster printer this year or a bench top CNC machine. ;)
