Dovetail spool holder

youmagine

The dovetail_spoolholder.scad file features two modules: a basic cylindrical spool holder and this module attached to a dovetail connector. The latter enables attachment to my dovetail wall connector (https://www.youmagine.com/designs/dovetail-wall-connector). It utilizes my earlier dovetail design (https://www.youmagine.com/designs/dovetail), so users must download the dovetail.scad file as well if they want to create custom-sized connectors. module spoolHolder: A basic cylindrical spool holder with a widened base and tip to prevent spool slippage. This module is useless on its own; it's designed for use in conjunction with a connector, such as the dovetailSpoolHolder below. Parameters: - length: Decimal value specifying cylinder length, set a bit higher than spool width for play. Default is global parameter Holder_Length. - wall: Decimal value specifying wall thickness. Default is global parameter Holder_Wall; minimum 1mm. - diameter: Decimal value specifying cylinder diameter. Default is global parameter Holder_Diameter. - base: Decimal value specifying base diameter, larger than holder parameter gives a 45-degree slope to bridge the gap between base and holder. Default is global parameter Base_Diameter; minimum is holder + wall. - tip: Decimal value specifying tip diameter, larger than holder parameter gives a 45-degree slope to bridge the gap between tip and holder. Default is global parameter Tip_Diameter; minimum is holder + wall. module dovetailSpoolHolder: The above spool holder attached to a dovetail connector. Parameters: - gender: Boolean value indicating male (false) or female (true) style connector. Default is global parameter Dovetail_Gender. - size: 3-value array specifying connector size (male/female combined). Default is global parameter Dovetail_Size. - margin: Decimal value specifying space between male and female connectors, may require experimentation to achieve a perfect fit. Default is global parameter Dovetail_Margin. - length: See module spoolHolder. - wall: See module spoolHolder. - diameter: See module spoolHolder. - base: See module spoolHolder. - tip: See module spoolHolder. Global parameters: - Holder_Length = 5; Set preferred length to avoid specifying it each time the modules are called. - Holder_Wall = 4; Set preferred wall thickness to avoid specifying it each time the modules are called. - Holder_Diameter = 20; Set preferred diameter to avoid specifying it each time the modules are called. - Base_Diameter = 40; Set preferred base diameter to avoid specifying it each time the modules are called. - Tip_Diameter = 30; Set preferred tip diameter to avoid specifying it each time the modules are called. Helpful functions: - dovetailGender(): Returns global parameter Dovetail_Gender. - dovetailMargin(): Returns global parameter Dovetail_Margin. - dovetailSize(): Returns global parameter Dovetail_Size. - holderLength(): Returns global set parameter Holder_Length. - holderWall(): Returns global set parameter Holder_Wall. - holderDiameter(): Returns global set parameter Holder_Diameter. - baseDiameter(): Returns global set parameter Base_Diameter. - tipDiameter(): Returns global set parameter Tip_Diameter. - female(): Returns true to indicate female style connector. - male(): Returns false to indicate male style connector. - yes(): Returns true. - no(): Returns false. - radius(d): Returns the radius of the given diameter. - inchToMm(i): Converts inch value to mm for imperial-minded users.
