RX Spektrum SR4210 Holder

thingiverse

I'm not a fan of fixing my receiver with double-sided tape, so I designed a holder and 3D printed one to make it easier for me to switch receivers between RC cars. The receiver comes equipped with AVC, which is a great feature according to the Spektrum site - it allows you to mount the receiver either flat or on its side. When mounted vertically, the receiver needs to be oriented precisely to ensure smooth operation. The housing of the receiver itself is crafted from two injection-molded halves with draft angles, so in reality, the sides are not perfectly flat. That's why I created a 3D-printed base with an exact replica of the negative cavity and drafts to fit the receiver snugly. Print Settings Rafts: Doesn't matter None Needed Supports: Doesn't Matter None Required Designing This Model I started by modeling the receiver itself. Once that was complete, I designed the base plate with a reinforced bracket for added stability. Next, I used software to remove the volume occupied by the receiver from the baseplate model. The final step involved designing all of the small details. During my initial print test, however, I found the fit to be too tight. So, I decided to increase the size of the receiver's 3D model by 4% and printed it again - this time the fit was just right.
