Customisable Filament Spool Holder

thingiverse

Changes: 08/02/2019 Added parameter tags for customizer Added a new quick release spool holder using Fibonacci's Golden Spiral Refactored the code to make it simpler to read This is a fully customizable spool centre for filament spools designed in Openscad. The source is here too so feel free to poke around! There are several settings you can customise to generate the spool holder you need. All dimensions are in mm. Spool Diameter The size of the hole in your spool Spool Width The width of the spool holder you want to create Shaft Diameter The diameter of the threaded shaft you will fit the spool onto Hub Length The length of the centre hub for the spool. If the shaft is shorter than the width of the filament spool, the centre can be recessed to allow you to fit spools that are wider than the shaft. Hub Diameter The diameter of the centre hub of the spool holder. Make it large enough to contain the hole for the threaded shaft Wall Thickness This is the thickness of the wall between the spokes and the spool. It should be set to zero if you are using the Golden Spiral Collar Diameter This is the diameter of the rear collar. It should be larger than the Spool Diameter Collar Thickness This is the thickness or depth of the rear support collar Edge Curve This performs a Minkowski transform on all external edges. It takes some time to render but gives really soft edges. Spoke Type blade This is a straight blade that uses the following parameters: wire This is a cylindrical wire (think of spokes on a bike wheel). You may need support to print this. spiral This is a Fibonacci Golden Spiral. You should set the wall thickness to 0 if you are using this as a single part. The spool will be a nice tight fit here so you can just pull the spool off to remove it. You should create a single spool holder that is the width of the actual spool. You will need support to print this as there is a section cut away at the collar end of the spool holder. Once printed, you should lightly press each golden spiral so it can flex freely as you push on the spool. Without this gap, the spools slowly move forwards and may fall off! auger This is a large corkscrew centre. You will probably need supports to print this. Spoke Count The number of spokes in the holder Spoke Thickness The thickness or diameter of each spoke Spoke Rotation The angle of each blade or spoke If you feel more adventurous, you can alter the spoke count size and rotation. I have included some example settings for all the images shown, but you can easily choose your own settings for this to come up with some cool options. Feel free to post your own settings here and I'll add them to the example list! The wire spools and auger will need support to print but the others should be fine without.
