Stealthchanger Dockable Nudge or SexBolt mount

Introduction

I tried the previous design and found my bracket was moving around a bit, and wanted something a bit more sturdy and perhaps simpler if possible. I also wanted something that would work with the Nudge or Sexbolt alignment hardware because my Nudge was not working well until I got the copper M3x6 SHCS. 

This uses the same 4mm pins from the StealthChanger build, but this bracket can be used with or without the bushings.  It was working great without bushings for me.

Oh, and Onshape CAD files are available!  Let me know if you have problems. 

Printing

• Use Voron specs for rigidity.  4-5 top/bottom, 4 wall loops, 40% infill.
• The files should be oriented correctly for printing.

BOM & Assembly

Bracket

Print the version for your probe. 

• (2) M3x4x5 voron heatset inserts
• (2-6) 6x3 magnets, depending on strength
• Insert heatsets and magnets.  
• Add 2 or 3 magnets for the bed and rear , depending on how strong you want it.

Bracket 2020 Mount

• (2) M4 x 12 dowel pins. one end rounded, other end M3 tapped. Same as the ones from Stealthchanger shuttle.
• (2) M3 x 16 SHCS for screwing in dowel pins.
• (2) 6x3 magnets
• (2) M3 x 20 SHCS for attaching bracket to 2020 T-nuts
• (2) M3 T-nuts

Insert 4mm pins and secure with the M3x16 screws. Add M3x20 screws for T-nuts and add T-nuts.  Secure to your 2020 rail just behind your bed.

Bracket block - no bushings (works for me)

• (1) M3x4x5 voron heatset insert
• (2) 6x3 magnets
• (2) m2x10 SHCS for attaching optional switch (optional)
• (1) M3x16 BHCS for attaching bracket block to bracket

Insert magnets and secure with glue. Add heatset insert.  This mounts to your bracket with a m3x16 button-head screw.  It goes on the “inside” of the bracket.

Bracket block - with bushings

• (2) 4x6x6mm brass bushing (4mm id x 6mm od x 6mm tall) same as stealthchanger shuttle
• (2) M4x (1) M3x4x5 heatset insert
• (2) 6x3 magnets
• (2) m2x10 SHCS for attaching optional switch (optional)
• (1) M3x16 BHCS or SHCS for attaching bracket block to bracket

Assembly is the same as the no bushings option.  If you have a Voron, you can figure it out.

Rear dock

• (1) M3x20?
• (1) T-nut
• (2) 6x3mm magnets

Insert 2 or 3 magnets, and then add T-nut  and secure to the rear of your 2020 bed rail.

Nudge attachment

• (2) M3x?

Sexbolt attachment

• (2) M3x?

Use

TBD
