OpenRC F1

Perfect combination of RC and Printing is the OpenRC F1 car from http://www.thingiverse.com/thing:1193309 so since it's now way easier to change color on my E3D Bigbox i started with thinkercad to easily create a color scheme.

BlackOps Razorback

A write-up on how i got to this..



I found the exported models online "here" so after download it was time to make it a printable model. Here is how i did this. I used lots of tools to go from a game model to a printable part, applied lots of fixes etc. Download the model here http://www.thingiverse.com/thing:1657532

Blender

Blender (https://www.blender.org/) is uses to convert the "game" file to something i can work with in other programs, also removed the so called bones from the model with blender. You probably can do a lot more steps with blender, you might be able to do all ... its just my skill level of blender that is lacking. 


add the plugin to open "game" files

import the model file



move the model to reveal the "bones" and delete them

export as STL

fixing them online


Autodesk MeshMixer

General purpace mesh editor (http://www.meshmixer.com/) again way more powerfull and capable then my skill set, but for me a easy mesh editor to make sure the model aint split up. 

download and install meshmixer

separate the shells, so it can be fixed


generate face groups so its easier to select the faces



extend the selected faces 

export as STL

second time repair this will now join the shells as the now overlap


Thinkercad

So now i had some decent STL's to be able to put the model together and add some weight, i added a hole in thinkercad (https://www.tinkercad.com/) i used a peice of M12 (for strenght its way overkill but it adds a decent amount of weight)

youll be able to see the added cilinder wits is a hole in thinkercad 

export the model.

Cutting it up


You'll need a really big printer if you want to print it as one piece, witch i don't. I was able to print it in 3 pieces witch are still large prints. You might want to cut it up in even more pieces (i added the full gun with and without the hole so you're able to do so).




Slicing


I sliced everything with simplify3D (https://www.simplify3d.com/as you can guess it needs a fair amount of support. I used the auto support and removed and added support manually (dont know any free software wicht allows you to do the same) 



Printing

Printing the model on my brand new E3D's Bigbox (http://bigbox-3d.com/) witch i who'd recommend any day. 

Printing the front

longest print so far




printing the middle



Longest print so far ;-)




looks small but its 60 cm in lenght

prepping for paint

after paint (airbrush) and glued together a few layers of satin clear

OpenRC F1 1:25

All things considered.. 0.4 mm nozel and no active cooling on the PLA it did not turn out all that bad.


Something is wrong with my printer, so for now only small parts can be printed. Nevertheless printing a 1:25 scaled version of the openrc F1 model went quit ok. I did cheat on the wheels and chassie parts.

Wheels are scale factor 0.41 and the chassis is 5mm thick. The wheels needed a bit bigger to get Cura to slice the model correct. The chassis is just for strength

Some pictures and the timeleaps video.







Banana for scale..
