Concept for new Technic parts

[D3K]

I was building some things yesterday, and I found myself wishing I had some pieces that I didn't have. Upon closer inspection, I don't even think they exist!

So I made a couple of quick renders to get your opinions on these two concepts. Is it just me being difficult, or would you also find these useful?

First is a piece That I could see many uses for:

The thing I needed this for was as a way to guide axles along beams using a minimum of space, sort of like this:

I'm sure there would be lots of other uses for that particular part.

Second is something with probably a little more limited potential:

I would use this to connect beams using thin liftarms, without having to use 3L axles with bushings on either side, like this:

So, what do you think? Useful? Or just me being high maintenance?

EDIT:

Also; please post your own suggestions for non-existing parts!

Not sure if I can do it myself, but maybe a moderator could change the name of the topic to something like "The new parts suggestions thread" or something something?

I think the first one would be very useful, and the second one somewhat useful, though rather more specialised.

Not sure if I'm hijacking by making my own suggestions, but two that I've come up with are:

• Two variations of the standard blue axle pin , one where the axle bit is 2L, and one where the pin bit is 2L. I've had a number of times when trying to build a rather dense studless desing in which one of these would have come in handy.
  
• A 2x2 PF "polarity reverser" plate. This needs a little explanation. It'd be shaped exactly like the plug that PF motors use to connect, but with no wires attached. One would connect a motor to an IR reciever (or battery pack or whatever), then put this plate on top of that, then connect a second motor on top of this. The two motors would then drive in opposite directions.
  This would allow you, for instance, to directly attach a motor to each of two wheels and drive them from a single IR channel. (When I made a direct-drive crawler with a motor on each wheel, I had to drive the left wheels from one channel and the right wheels from another, and attach the levers on the IR remote together so that they worked together, with one reversed).
  It would also allow much simpler installation of an adder, as each motor could directly drive one input to the differential. I imagine there's other applications.
  I doubt TLG would find enough use in actual models to produce this, but I think it'd be useful for MOCers.

Barman has already recommended the first one (and a lot of other good stuff) here. The second part in the image below now exists. Thanks LEGO!

You can make the first one pretty easy if you don,t mind modding a double of it. Just cut one side off and smooth out the side, n you have one.

There , just made one, now if only I could figure out how to post pics on this bloody site. Barman has some cool ideas on these and related pieces.

Blakbird has post his Brickshelf page above if thats what you mean?

[KopMaister]

Love them! the double halfpin would be my favorite piece if it existed!

[skylinedan]

No, I was commenting on the pictures of Barman,s ideas. I got one out, cut one side off then took a file to it smoothing it out nice. Looks good other than needing a little buffing to shine it up like the reats of it.

I once did that to to get these:

good if you're in a hurry and cant do a BL order

[Paul Boratko]

I would like to see this perpendicular connector with 2 axle holes instead of one axle hole and one pin hole... The only problem is that Lego would probably make it in bright pink so people wouldn't confuse it with a traditional one when following instructions because I know people have used it with the axle hole in the wrong places thus preventing an axle from turning...

[rumpletump]

What about these parts?

I don't think they exist already but correct me if i'm wrong

I modeled these up pretty quick so please ignore the messy CAD work haha

I too could've used those parts on veveral occations! I suppose you mean something like what rumpletump rendered here:

Damn, looks like somebody beat me too it!

It's cool the 'Technic Pin Long with Friction and Center Pin Hole' (87082) now exists!

Had a llok in his brickshelf folder, and there are definately some nice concepts there! But two stand out to me;

1. The 2L "tubes" that look like "Technic Pin Joiner Round with Slot" but with added "clutch" like on the old type 1/2 bushings. Brilliant way to transfer two rotational forces along one axle not using more than 1x1 of space, and having no delay like now (vertical axle through the turntable on 8043)

2. The ball joint (kogellink) arm where you can choose which way to mount the connectors.

[efferman]

i think a part like this would be nice, to be more flexible in building axles

[allanp]

I like both your ideas, especially the double half pin. Instead of me hijacking this thread, maybe we could keep it to the most fundamental of parts like pins and connectors.

[jovel]

Nice parts!

I also designed a part to get three functions through a turntable:

I know it's possible with existing parts but this is more compact.

great! this is the piece I'd love most.

just one side note, given that it's about designing a new part, I would avoid using the 6542 , because it introduces backlash.

using ordinary LEGO pieces, I avoid that by using a differential for passing the second coaxial function thru the turntable.

that would need to be a whole piece (not meant for disassembling into its component parts).

also, extending your design, there could even be a 3-coaxial thing, for passing 4 functions thru turntable

[mescalinum]

I often found myself needing this part - the right one, which is the converse of the left one:

hey someone should track all those unexistent pieces somewhere… like a gallery of broken dreams

if I remember, this topic already appeared in the past

[GuiliuG]

I really love your idea Jovel ! I guess it would be quite interesting for a lot of other MOCers.

Personally, I would like to see an epycicloidal geartrain from lego, so you can put important hub-reductions or build some automatic gearboxs.

And strangly Crowkillers, I would prefer the connector you show with two pins holes ^^.

Mescalinum : one part more I hope lego will ever release...

Pretty close:

[Laurens-wuyts]

I was thinking on a 45° technic pin. like this one.

Than you could connect plates on 45°.

....can we have them all XD?

Too fragile!

[N-4K0]

I would like to see Blackbird, rumpletump, efferman and mescalinum's ideas come to life, they could be pretty useful.

[JohannesESTONIA]

I made these pieces a while ago, cause I really needed do use them. Just cut one end off and ok.

[SNIPE]

if lego made this then we would be able to have :

and but with 2 thin axle holes or one axle hole thick, centered.

with one or two of these (on the left)

I hope Lego makes these since it means the wont need to make loads of bricks that are more limited which costs money for the moulds, materials, labor etc, there will be more bricks with more function instead.

[efferman]

new rims please,

maybe with an crosshole in the center
