Simple spool rack/stand

This is a basic filament spool rack/stand. It is NOT stackable, modular, labeled, or multi-color. It requires no supports. Most importantly it doesn't require you to get additional hardware. It is a stupid-simple print that allows you to stand your spools on a shelf without them rolling around. Perfect if you already have a shelf and just want to store your spools vertically. It has 2 recessed screw holes to secure it in place if you feel it's necessary. It does work fine just sitting there so screws are optional. The model is 220x100x13 and scales fine length-wise. You should be able to adjust the X-axis up to 250 or down to 150 for a mini, although the screw holes may be ovals. I don't recommend scaling the width or height as they provide the curve that matches the spools. The default length of 220 holds 3 spools. Print time is 2h 14m, and uses 72g of filament. You can fit 2 on the bed if you need multiples.
