PCB Circle-Drilling and Milling Aide
thingiverse
This tool enables users with a table-drill to effortlessly drill holes along circular curves on PCBs without adjusting coordinates frequently. To use, drill a 5mm hole in the center of the circle, attach it to the 5mm parallel pin on the PCB drilling aid, and align the drill with each hole before drilling. Precise alignment is key for accuracy. The device is particularly beneficial for LED lighting projects but can be used for various purposes. Printed with 0.25mm layers, 4 solid top/bottom layers, 4 shells, and 50% infill, it requires a 5m6 x 15mm parallel pin for functionality. A round soldering pad in the circle's center helps with precise drilling. Use at your own risk and hold onto the PCB at all times.
