Whiteboard Tray and Cup, modular, parametric

thingiverse

This is an extension of thing:1037034, courtesy of hemocyanin. I added the Cup, which is customizable so you can figure out what to do with it. Personally, I use it to store my pens, but you can adjust the parameters to fit your eraser or any other idea that comes to mind. This design is optimized for 1.75mm filament. Here's some original explanation: This tray will work with any whiteboard that has a frame made of a channel material which accepts a T-shaped rail. It won't work with frames that don't have this channel, such as solid wood frames. The default sizing is based on the whiteboard I bought and used: http://www.amazon.com/Master-Boards%C2%AE-Drywipe-Magnetic-Whiteboard/dp/B00TQV2X8G. __Note:__ The defaults in Customizer and the STLs I've included are optimized for a Lulzbot Mini with a 0.5mm nozzle and 3mm filament. If your nozzle isn't as wide or you want to use cut sections of 1.75mm filament to make pins, you'll need to adjust the parameters in Customizer for proper fitment. Assembly is simple: just slide in the correct end-piece, then all the intermediate tray sections, and finally the other end-piece. Each piece is held together by pins, up to three per side, though it may not be necessary to fill all the pin holes. The only potentially confusing parameters involve the T rail. Use this image as a reference for making adjustments to the T rail: https://cdn.thingiverse.com/renders/82/c8/be/be/d3/1305cfbb39ab41659112500d78d4e269_preview_featured.jpg
