PCB holder for STM32 Discovery board

thingiverse

A bare printed circuit board full of pins is extremely frustrating when it scrapes against the surface of the table. This handy holder keeps the PCB safely elevated above the table, giving users effortless access to the GPIO pins at all times. To use this clever device, simply extend the arms and slide the PCB between them until it clicks into place securely. The concept can be easily adapted for other printed circuit boards as well, making it a versatile tool in any maker's toolbox. When printing, make sure to print horizontally as seen in the pictures. Printing vertically can lead to "broken arms," so it's essential to get it right from the start. After printing is complete, extract the support material from the slits and take special care with the corners to ensure a smooth, clean finish.
