I think for the 3D printing part of the site it would be useful to be able to search the models also based on how easy they are to print. When it comes to 3D printing you usually have the people who know exactly what they are doing and then the newbies who have never printed anything. I think it would make sense to have a distinction between easy prints that do not need high level understanding or knowledge of using support materials, special temperature settings because they have to be printed in ABS or else they won't work etc... in one category and then the easy plug and play prints in another section.
I noticed this since now I have a 3D printer that a lot of the fancy rings and Jewerly models are challenging to print as opposed to some other nik nacs or toys for instance that have a perfectly flat surface adhere directly to the build plate. Also some of the models are like a billion polygons so when you import them into Cura, Mattercontrol repetier host etc... if you need to modify them it is a huge hassle. Rotating, scaling even adjusting the position can cause a low end PC to crash or just stall for a long time. That also causes slow downs when the packets are being transferred from the SD card or USB cable to the printer making for slower print times.
When you are a 3D printing pro and have a high end PC non of this matters or affects you but we all know that there are plenty of buyers who are just students or 3D printing noobies and I think having a section dedicated to them would be helpful in getting more people to get interested in 3D printing and buying 3D printers etc... attracting more buyers to CGT
These days when people buy a 3D printer and they have no clue about 3D printing they get discouraged very quickly. The machines are quite hard to operate and most prints are very challenging to build.
The less hassle buyers have to go through the more likely they are to come back and buy more from us.
