This is a holder for pens, markers, & pencils to turn your Onefinity CNC into a drawing machine! It’s super simple to create toolpaths & make perfect works of art for all occasions! This is ‘spring’ loaded, the design is ‘springy’ without the need for a metal spring, so there is some ‘give’ when drawing to give even pressure. This is the perfect accessory to get the kids involved. You don’t need a to have the loud router running when using this! Bonus! What you will need (does not come with) - 4 M5 bolts to hold the holder onto the z slider. - 2 fully threaded smaller screws to go through the front two mounting holes to ‘secure’ the pen/pencil/marker in place. Anything you have laying around the shop should do! Just be careful when tightening to not snap the 3d printed part. This is 3d printed in PLA. I typically print in black unless I’m out of stock. You may get a different color. Onefinity Cnc Pen, Pencil, Or Marker Holder. Turn Your Into A Huge Drawing/Plotter Machine Create Awesome Artwork Easily Physical
