Nice render you have there… :-/
Is anyone else tired of seeing people showing off CAD models of printers/CNC machines? Like, yea! Great! Does it work? Are you ever going to make it?
Yes, I’m guilty too, I never made the below printer out of 40x40mm extrusion, it’s pretty stupid.
I’m loving that the parts available to us now mean we can pretty much arbitrarily nail together working machines out of well tested off the shelf parts. I.e. this extruder on this nozzle under this electronics in some frame I’d like to try.
But seriously, we see so many models presented like finished products and so few actual machines. I’m all for requests for comments, it can only serve to help one or all of us.
Am I being an unreasonable misery guts?

Borrowed your extrude scad files.
Well the time for getting input on a custom printer is when you are in the design phase. That means cad/renderings to show a concept. I love seeing them as I like to see what others come up with. The amount of custom 3D renderings that actually become real working printers is probably pretty small but the same could be said for anything else in the product design world. You start with a napkin sketch, then some loose 3D, then some tighter CAD models for engineering purposes, and finally a real prototype.
Yea, I think they come in 2 flavours. People posting an RFC and listening to ideas, I like these. But there’s also people posting “Finalised” over-complicated designs that already have a fancy name and are sitting on thingiverse having never been printed, let alone tested.
I don’t put up my designs until I actually build or test them. Until I do, you’ll be seeing a lot of concept rendering.
I tend to upload things I’m working on to my github account and never tell anyone. Theres a lot on there that I never got confident enough in to share here or publish, also the odd thing I probably will share but I need to test some more first.
PS. Still using your electronics on my machines. Propper little workhorses.
I think sharing designs is great, There is nothing better than fresh idea being shared and this can go both ways when you post a design online. however i think it largely depends on how far into the design stage they are. the image above is terrible because there is nothing to give to the community and the community cant really give you any advice either.
I should probably post more of my designs here on G+. I do post finished builds but those’re way rarer than concepts 
All my concept render stuff goes on a Google Group to a small community but y’all would probably enjoy some of the oddball stuff.
I find and incorporate ideas that come from seeing this kind of models but, as a noob to 3d printing I would say you are right in that there is a lot of concept and very little follow-through. It was hard to find good concept to build info, and I could of really used it.
I do wish I had been part of this G+ community when I was designing my 3d printer, so I could have benefitted from the vast knowledge freely available, Thank You, but here is a link to what I have on G+ from the beginning, minus the latest (–)(https://plus.google.com/u/0/collection/sSyBSB)
I think you see many concepts and relatively few working projects is that the designers have access to modeling tools but not necessarily the means or methods to execute the ideas.
Many of them aren’t realistically designed for manufacture, some are unnecessarily complex. When it comes to time to implement the ideas one impact is the cost of iterating the idea. Basic quality components are at a minimum a few hundred dollars to several hundred dollars depending on the design. I see that as the stumbling point for most of those designs. Other simpler, low cost designs may lack the technology to implement the designs. It can be expensive to try and build inexpensive things.
It says borrowed your Extruder scad files but shows no Extruder, lol. What on earth is this?
@Andrew_Hodel Extrude, not extruder. I think he is talking about the frame.
I do a lot of concept and I put a lot of thought (at least I believe so) into what I am designing. I have a technical background and I post my designs on thingiverse and here but I don’t have anymore a 3d printer and my life takes me allover the continent so I can’t really have a printer carried from place to place. Thus I post for others to take notice and get ideas, maybe better than mine. I do a lot of research and I am happy to see may designs and many concepts and many builds. That’s the way creativity is cultivated.
Hey my printer is off 40mm extrusions 
Which one @VolksTrieb ? Metric Cerberus?
@Bracken_Dawson 40mm Item-compatible profile
