Efferman's Custom Parts

[MRP_]

wow, you must be working in quite a large scale!

[efferman]

Hi efferman

I am building a Land-Rover Series IIa (a copy of my real life car). For that project I need some leaf springs that should be larger. The Land-Rover has different sizes front and back. For my project I need two springs 13 L and two springs 19 L.

I would love to get your design in those sizes. :-)

Best regards

Welcome on eurobricks. do you need them fast or can it wait two weeks? i have a exhibition on 10.9 -11.9 2016 and i want to bild a xerion saddletrac for this exhibition

Hi Efferman,

Finally I have ordered the clamshell buckets last night.

Will be getting them on October 3rd or 4th.

So as a back story, for the next few months I will have access to a 3d printer, and was thinking of designing some wheel covers for Lego wheels. But I was wondering, from people who have designed many parts before. How do you go about designing some, from somebody who has never used software like this before

 

Are there measurements in the software that relate to real life? How difficult is it to design it? How long does it take? Are there any tutorials for Lego specifically? How strong are they? How easily can they be painted? 

 

Even if you can only answer a few, it would be nice to know, beforehand 

[efferman]

First rule at beginning, keep it simple and learn the softwarefunctions. Then search for a original which is possible to create.  Can i ask which type of printer do you will use?

 

[Buddy010702]

I believe that it's a maker printer, nothing too special. 

 

What software do you suggest, I assume the one you use?

[efferman]

The one i am using is a proffesional software which costsa few thousands of dollars. But when you are a student you can get a school licence of autodesk inventor

[Buddy010702]

Ok, thank you, I'll try to get autodesk inventor. Thank you! If I make anything, I'll post it here.

Efferman, do you think you could send us a link to the stl files for the 3rd edition turntable?

 

[efferman]

Please give a link to the turntable to be sure we talk about the same turntable

Also, using a formlabs form 2 printer I was able to print the first turntable you made without having to do any sanding!!

Efferman, is it possible to create this part with a 45 Degree angle, and one with like a cross shape -0- and T shape?

Effer...someone bought some parts and did a video review:

 

[efferman]

many thanks for posting. it seems the small drven steering hub needs some tuning

[Milan]

Nice presentation, Richard! Thanks!
That small diff has always been so appealing to me! Maybe one day I will cross to the dark side and take one (or ten) of them.

I have purchased for 8 "Wormgear Counterpart" , https://www.shapeways.com/product/WBXDZK8E7/wormgear-counterpart?optionId=43734647
This is a very good work. All fits very good. Thank you.

Does  this wormgear counterpart work with Lego worm gears to perform linear movement ?  

[efferman]

yes

Hey Efferman

I was wondering, can you print axle and axle related parts with good enough precision? Ive been mulling over true boxer engines, and come to the conclusion that with a modified engine crank (the axle pin needs to be 1 stud long rather then 1.5) and a modified conrod (it needs some plastic taken away on one side to allow for it to fit into a smaller crank) you could build a 2 cilinder true boxer engine, with the cilinder offset half a stud. Add to that a custom 1.5 long axle and you can build arbitrary length boxer engines.

I know i can build this by modifying existing parts (namely grinding off some bits of the crank and conrod parts), but custom prints parts would be nice too.

[efferman]

Cross axles are a big problem. The tolerance in printing is not good enough to fit crossaxle and printed part together in a safe connection. In your case i would prefer a one piece crankshaft and clip the piston rod on it.

Hmm, i see, i might just go down the modifying real parts route then, considering a one piece crank (which in the end would still require either a cross axle, or a cross axle receptor) would pretty much limit me into specific single configurations in terms of cilinder count etc..

 

Bit of a bummer, but modifying existing parts was always going to be more cost effective, considering crank or con-rod pieces only cost a few cents each on BL.
