Magnetic Penholder for Whiteboard

youmagine

To keep my whiteboard pens neatly organized, I crafted a compact dual pen holder specifically designed for my board. The pen holder is secured to the board via four sturdy square magnets. To ensure a seamless fit, look for 7mm x 7mm magnets that can be pressed snugly into the mounting holes without requiring any adhesive. If smaller magnets are used, they will need to be glued in place using epoxy glue, which I find effective for this purpose. I printed the pen holder file with Cura software, utilizing a moderate infill setting of 20% and a speedy print speed of 80mm/s on my Ultimaker UM2.
