## Description

"Haydn's Carbon Fiber Arms with CNC Machined Delrin Sockets" Available in 215mm, 304mm, 360mm and 400mm ball center to ball center lengths! Delta Printer hackers/makers/builders: This fully assembled Precision Magnetic Arm Delta Solution comes with 6 carbon fiber rods, 12 precision machined Delrin cups with embedded magnets, and 12 ball studs. All arms are precisely assembled, and hold tolerances of less than 50µm (ball) center to center dimensions using custom jigs. (Note that arms in the market with substandard tolerances make auto calibration more difficult or even impossible) All Magnetic Holder Cups are precision machined from black Delrin. Delrin has great material properties for 3D delta applications! It has high wear resistance, low coefficient of friction (reducing energy loss through friction). There is no need for lubricants, and will reduce overall noise on your delta. All joints are also tested to at least have 1.5kg holding force on each end. The Chrome Ball Studs are cleverly designed with hexagonal base for easy tightening and standard M3 threads that would easily adapt to popular carriage and effector thread sizes. Carbon fiber is the choice material for the rods, which have a high strength to weight ratio.

## Customer Reviews

### ⭐⭐⭐⭐⭐ well made
*by S***I on September 19, 2018*

these things are without doubt the best rods i have tried, the standard are thin and weak with some wobble in general but these things are solid, no wobble on the effector what so ever, these things are great, improve print quality several times over, i would highly recomend these

### ⭐⭐⭐⭐⭐ A very good upgrade
*by G***S on August 28, 2017*

These have greatly improved my printer. The arms themselves are excellent. The balls are not as high a quality as there is some diameter variation but they are close enough to do the job. I would recommend them to anyone.

### ⭐⭐⭐⭐ Works as advertised.
*by A***R on September 14, 2016*

2 of the rods did not have the sticker indicating the length which is crucial for installation. Please use another method rather than the stickers which can fall off. The craftsmanship appears good - but not GREAT. I would purchase these again and I probably will when I build another delta.
