3D Model of a Menzi Muck A81

I only have seen one of those in real time once. But the pictures on the internet, what this backhoe can do is amazing.

Since my future layout will have some really steep inclines, I started to model a Menzi Muck in Sketchup. I base the model on a free available papermodel which might be not 100% accurate. This is as far as I got right now.

It is almost finished for printing. I need to add little details and reduce the wall thickness to save material.
Right now everything is designed to move but they might be too small for that. I might have to put it in the right position and apply glue, which would not be that bad.

@engineshop   THAT IS AN AWESOME CAD MODEL!!

Have you thought about how you could articulate it?  I know asking for miracles!

John,

The model is designed for 1 and 1.5mm micro brass tubing. I assume the friction of the tubing and rods will not be enough to keep the pieces in place. I will know more after printing.

I added more details after I found better close ups of the original.



I also had to change some parts until the initial test from Shapeways did not flag any problems anymore. I hope their manual check will be successful as well and I soon can show off the model here.

That is a very detailed model Roland. Nice!

Peteski,

I use to get a little overboard on the computer with the details.

I just received the 3D print from Shapeways. I put together the rear wheel assembly and it moves as intended. I still have to attach the hydraulic cylinders (made out of brass rods).

That looks really good - and it is articulated too!  8)

BTW, the name of the vehicle looks to me like some derogsatory name you would use in the English language.  Like:  "You menzi muck, go and clean your room - it looks and smells like like a pig sty!"  :D

I can see the problem in English language. The founder of the company is Ernst Menzi. He named his backhoe after a German fairy tale character: "The little Muck", which is pronounced Mook.

A little history can be found here: http://www.menzimuck.com/en/company/history/

On my layout, I want to recreate this pictures: http://files.site-fusion.co.uk/webfusion101074/image/anw-11g.jpg

Thanks for the info. Fairly tale character. Interesting. . .I just found the name amusing. You are right about the pronunciation. In English "muck" means something else: http://www.merriam-webster.com/dictionary/muck

Peteski,

I use to get a little overboard on the computer with the details.

I just received the 3D print from Shapeways. I put together the rear wheel assembly and it moves as intended. I still have to attach the hydraulic cylinders (made out of brass rods).



@engineshop Very, very impressive.  I know this is a test for you.  You might consider some micro rivets for the pivots with a dot of solder on the underside.  As fara as soldering heat, I have found that FUD and FXD are very heat resistant, to the point where I have poured molten lead into a printing, just to see how it would fare.  Let's just say i was pleasantly surprised.

John
Thanks for the tip. I checked out the neat stuff they got but I would have to re-design most of my holes to accommodate what they sell. I just use regular wires.

I just finish the first test fit. It took a little bit longer since I made over 50 improvements. All parts are moving like the original but I still will glue the pieces in place since the cylinder don't have enough friction to keep the parts in place. My little model is feeling the effect of gravitation and everything is moving downhill. Once it is a part of my layout, I will not adjust it anyhow.
All the parts have to go through Shapeways test again but then they are ready for the second printout.

That is a very cool construction vehicle - I can't wait to see it painted.  I never seen anything quite like in USA even though it looks very maneuverable and stable.

Ok. That is just plain impressive. 

Hats off to you.

One thing you could do to allow for complete adjustability is squeeze the end of the rod that goes into the tube ever so slightly so as to cause a slight interference on the I D. Of the tube.
