Pegboard

prusaprinters

Basic Pegboard NOT Metric. Sized for common 1" pegboard hooks. 8" Square, fits on most printers. Great way to get organized and use up your scraps of filament. I recommend printing with a brim, and keeping the number of bottom layers low. 4-5 so that it won't warp as easily. I printed it at 0.2mm but there's no need for  thinner layers. Since it's all vertical geometry, you can go as thick as you want. Use #6 Flathead screws, 1" or longer for mounting, depending on what your attaching to.
