Lego Technic Connection Plate for Remote Control Car

My family loves Lego and we love the Lego Masters show. A couple of the seasons had car builds which we thought was a cool idea. My wife is a technology teacher and part of her curriculum uses Lego. We looked around for the cars used on the Lego Masters show and found they were custom-made and not cheap ($$$). Not even sure you can purchase them. This led me to look at doing something on my own.

This solution is not perfect. You cannot build huge things on these cars as they are not meant to hold lots of weight. Still, I think it will work for my wife and maybe somebody else.

I have included 2 versions. One is a solid plate and the other has cut-outs used to cut down on the weight.

I am also including a model of the bar used to connect the Techic bricks and pins. It took a bit for me to get the measurements correct so the pins fit and snap in. I thought somebody else could use this for their project. 

I used Technic bricks and pins to connect to the plate because designing a Lego part that snaps cleanly to real Lego bricks can be tricky. 

I used the BEZGAR 1:16 Scale High-Speed RC Car (Model: HP161) (https://a.co/d/2inKaDC). No modifications need to be made to the car. The holes in the plate fit over the pins used to hold the car shell. I bent some paper clips to slide into the holes at the end of the plate. These go through the holes in the pins on the car. I put some groves on the bottom of the plate that can help with bending the paper clip to the correct size. Note that the front pin holes are a little angled so you will need to bend the ends of the paper clip a little to get them into the holes. 

If you want to use this with a different car, you can pull the model into Tinkercad or some other design program and create new pin holes. 

I printed this in PLA, .2 layer height, with the flat side down. 

The only supports needed are for the open version. You will want to create manual supports under the bar with the holes in it. The solid version prints with no supports.
