SexPillar

SexPillar is an advanced, fully parametric endstop, drawing inspiration from Unklicky, Sexbolt, and Unklicky_z. Crafted with meticulous attention to detail in Fusion, the design file encompasses a wide range of possibilities and is annotated with comments to ensure ease of use. Tailored specifically for printers with a metallic plate, it incorporates a robust magnet at its base. This magnetic feature not only ensures stability but also facilitates precise adjustments along the X and Y axes. Moreover, its adaptability shines, as it can accommodate any magnet, screw, wire, and heat insert. Primarily, SexPillar is optimized for use with an auto_Z macro, streamlining the calculation of nozzle offsets and babysteps.

Disclaimer

This bill of materials is based on what I had readily available. While the associated .f3d file is fully parametric, I do not recommend purchasing the items listed verbatim. Instead, evaluate what you have on hand and adjust accordingly. Larger tower(Tube Height) and window dimensions (HWC) may offer greater ease during assembly. In essence, with the right specifications, you could construct the 'sexpillar' using just one screw, one sexbolt, two magnets, and two wires. I incorporated numerous heat inserts in my design due to my personal preference and because I had an abundance of them.

PS: if you do change Tube Height, remember to also adjust PinHoleHeight

In the Fusion file, all elements are parametric. However, the hardware is primarily for initial visualization. When adjusting parameters, the hardware may not align with all parts. For a clearer view when modifying parameters, it's recommended to hide all hardware.

Update 10/20/2023

Added a bracket version for using with T-slots and any kind of screws to attach it, also totally Parametric

Information and pictures of added parameters in the end

Update 10/24/2023

I was unable to find a program or program myself to babystep a bedslinger with sexpillar :/..., but i tested it and it works wonders as an endstop, so i am sure a lot of people will find use on it

right now i just modified my printer.cfg and i am using as a button, in my case scenario that i am always tweaking my printers i was missing the option to move my printer without having to Home or g28.

so i just added a SET_KINEMATIC_POSITION, you could use as anything i think even as an emergecy button might work.

this is my code in case you want to do something, please be carefull SET_KINEMATIC_POSITION is dangerous if you don't know what you are doing. also SET_KINEMATIC_POSITION just works if force_move is set to true.

press_gcode:
    M118 Please home as soon as possible
    M117 Please home as soon as possible
    SET_KINEMATIC_POSITION X=150 Y=150 Z=0

Parameters

• BMD (Big Magnet Diameter):

  • 20 mm
  • Refers to the diameter of the larger magnet used in the design.

• BMH (Big Magnet Height):

  • 5 mm
  • Specifies the height of the larger magnet.

• SMD (Small Magnet Diameter):

  • 6 mm
  • Diameter of a smaller magnet

• SMH (Small Magnet height):

  • 4 mm
  • The height of the smaller magnet.

• HD (Heat Insert Diameter):

  • 4.3 mm
  • Diameter of the Bigger heat insert

• HH (Heat Insert Height):

  • 8 mm
  • The vertical size of the Bigger heat insert.

• TPH (Tolerance of Printer in holes):

  • 0.6 mm
  • The Printer typical Tolerance

• NozzleSize:

  • 0.4 mm
  • The diameter of the 3D printer nozzle

• Wall:

  • 4.8 mm (12 * NozzleSize)
  • Thickness of the wall, calculated based on the nozzle size.

• DMG (Distance from magnet to ground):

  • 0.6 mm
  • This gap ensures the magnet doesn't touch the base or ground. so it doens't scratch, too big and you will not have a good grip too small and you will scratch your table.

• LayerHeight:

  • 0.2 mm
  • Each 3D print layer's height, determining the print's resolution.

• WSM (Wall separating magnet):

  • 0.6 mm (3 * LayerHeight)
  • The thickness of the wall that separates individual magnets. too small, weak wall, too big you have a problem with magnetic not having enough force to push.

• DP (Diameter Pin):

  • 8.4 mm
  • Refers to the diameter of a pin used in the assembly.

• PHe (Pin Height):

  • 25 mm
  • The vertical dimension or height of the pin.

• FP1 (Flatten Pin adjustment):

  • 1 mm
  • Amount to reduce the pin's side.

• FP2 (Opposite side adjustment):

  • 1 mm
  • A similar adjustment as FP1 but applied to the opposite side.

• SCD (Screw Contact Diameter):

  • 3 mm
  • Diameter where the screw makes contact

• TSW (Tolerance Screw Window):

  • 0.6 mm
  • The allowable deviation in the screw placement window to ensure a proper fit.

• HWC (Height Window contact with added half circle):

  • 3.6 mm (SCD + 0.6 mm)
  • Refers to the height of the contact window that includes an extra half-circle design.

• TSexyBolt (Thread Sexy Bolt):

  • 5.5 mm
  • The length of the threaded section of "sexy bolt". You need to edit this directly on the design timeline.

• HTsexyBolt (Height Thread SexyBolt):

  • 4 mm
  • Specifies the height of the threaded of the "sexy bolt".

• TubeHeight:

  • 35 mm (PHe + 10 mm)
  • The vertical dimension of the Tube.

• SHD (Small Heat Insert Diameter):

  • 2.7 mm
  • Diameter of a smaller variant of the heat insert.

• SHH (Small Heat Insert Height):

  • 3.5 mm
  • Vertical size of the smaller heat insert.

• SSD (Small Screw Diameter):

  • 2 mm
  • Diameter of the smaller screws used in the design.

• PINholeHeight:

  • 16.4 mm
  • Represents the depth of a hole specifically made to accommodate a pin.

• Teste

• Moving

Parameters MOD Bracket

• DFM = Distance from middle
• DFG = Distance from Ground
• LB = Lenght of Bracket
• HB = Height of Bracket
• AB = Angle of Bracket
• DFS = Distance of Brackets
• SBS = Screw Bracket Size

Keep in mind that you just need to make visible the bracket that you want then you go to component and save as mesh, this parameters change both options. there is a horizontal and vertical brackets, and they can change angles
