This is my first model.
It a sandpaper roll dispenser with a magnetic lid and should be compatible with gridfinity. it designed to fit 100mm width sandpaper roll with a max diameter of 65mm. It has a serrated blade that is attached with 3x M3x8mm counter sunk screws. I'm not so sure the efficacy of it but seems to work and just there to handy. The lid is attached with 8x 6x2mm magnets and has an angle on one side so you can push down and the lid should angle up letting it be accessible but still sit flush. Be careful with the orientation of your magnets if you plan on stacking it with other bins with magnets. i left the sides blank so you easily add what size grit yourself in your slicer.
It shouldn't need supports. I printed it in petg with the stock bambu 0.2 slicer setting.
I'm still pretty new at modeling and designing for 3d printing, so feedback would be great.
It was inspired by another model by 3docity.
