Calling all CAD pros - little help needed for a modified NERF gun

Morning all,

I've taken a slight break from robots since I got a bit interested in modifying NERF guns. A simple google on the topic will show you what it's all about!

The gun I'd like to modify uses electric flywheels to propels the darts so my natural reaction is to put in the fastest possible brushless motors that seem suitable, which should see more than slightly better performance than the stock set-up. However, to do this you need a new 3d printed motor and flywheel mount aka a motor cage, and I've found a suitable one on thingiverse which is perfect but its motor bolt pattern is for a specific 2205 motor whereas I'm planning to use some 1306 4000kv motors I've already got. Essentially all this requires is filling in the old mounting holes in the 3d model and creating new ones but this is completely beyond my complete lack of expertise, plus when I try to import the file into fusion 360 it becomes a mesh which I can't convert into a solid shape? Therefore is there anyone on the forum that's willing and able to help me with this? After I've printed and tested it, I'd then want to reupload to thingiverse as a remix of the original if whoever modified it was in agreement.

Cheers

Dan

I can do it but don't have the time atm. Will be free at the start of next month.

Are the original files publicly available, I could have a go with solid works Maya plus others

Can probably have a go at this tomorrow morning if you link the thingiverse page and the motor you are using.

Cheers guys.

This is the link to the motor cage: https://www.thingiverse.com/thing:2561650 (you'll see there's cut outs for the motor wires already that'll need to line up)

and these are the motors I'm using: http://image.helipal.com/emax-rs1306...-cw-big003.jpg

Would also be great if someone could reduce the size/ simplify the flywheel file as I can probably manage to alter that myself in tinkercad.

Cheers!

Sorry to bump this but has anyone had any luck with this? Ive now dug out the motors so can take any measurements required.

Oh sorry I didn't realize nobody had actually got back to you. Will do it tonight when I get back from work.

Thanks dude!

I managed to remove the holes, but can't figure out how to make new ones. STL is such a shitty format for models, why don't people just print step files...

You can just print the part out and drill the holes yourself. Using the motor plate as a guide.

cheers mate. I'll give it a go!

You need to make a new model with the holes as pins arranged correctly and carry out a boolean subtraction to remove the pins from the original part to make the holes.
