Mostly Printed CNC Primo J-25.4mm MPCNC - Cable/Drag Chain

Wasn't a fan of what I was finding online for a cable chain on the Z-axis of the MPCNC Primo. Decided to design my own and it works great. This is for the J-25.4MM Version. 

Hardware needed for this:

• 8 x M3x5x4 Voron spec heatset inserts (2 in each truck clamp, 4 for the Z clamp)
• 2 x M3x6 flat socket head screws - right truck clamp
• 4 x M3x10 flat socket head screws - left truck clamp and z-chain mount to cable chain
• 2 x M3x18 socket head cap screws - Z-clamp
• R28 Internal Size 15X15mm Cable chain, comes in 1 meter sections on amazon
• 1" by 1" Aluminum L-Channel, 1/16" thick, get as long as you need. Picked this up from a local hardware store called Menards.

What you need to print to get this installed:

• truck-clamp-j-primo-dragchain-left
• truck-clamp-j-primo-dragchain-right
• z-dragchain-clamp1

Then you need to chose one of the two:

• z-dragchain-clamp2 - flat mounting point for z cable chain
• z-dragchain-clamp2-raised - raises cable chain up about 14mm

Not required but helpful templates to mark/drill holes in the aluminum J channel.

• truck-clamp-j-primo-dragchain-leftTEMPLATE
• truck-clamp-j-primo-dragchain-rightTEMPLATE

Truck clamp was completely remodel to include features to hold 1"x1"x1/16" aluminum L channel for a cable chain.
