I was tired of the filament holders just sitting on the table, unsupported, they'd move and slide.

I was also tired of the spool coming up when there wasn't enough weight in the spool itself to stay down.

I then was just bored, wanted to try and make something of my own to see if I could do it.

The base is measured out for a filament holder of 169 cm long and 24 cm wide

These values are to allow space for shrinkage, but they fit like a glove.

The Screw is designed to fit straight across, not to hold the spool, but hold it in the build.

The main build can be printed unsupported, while the screw needs just some low level support for the built in washer.

Feel free to modify it further for your own needs

Well i could, and i did, and now it's done :)

You can always add negative space to free up material, use double sided tape for the bottom, or add some mounting holes if you like, this was really just for fun.
