Description

This is a simple carriage which works with magnetic ball joints and Delrin or POM wheels.  You can get the wheels inexpensively from DeltaPrintr.com

This works nicely with my magnetic effector:  https://www.youmagine.com/designs/kossel-plus-magnetic-effector

And with my magnetic ball joint rod ends:

It is based on my more universal Kossel carriage:

Contact me at haydn.huntley@gmail.com if you need an inexpensive source for the ball studs and/or magnets.
2014-08-17:  Slightly improved the design.  Added a lip to better trigger the endstop switches.  Made the ball stud nut traps shallower.  Changed the angle for the ball studs from 30° to 45° to optimize the amount of freedom they offer.

Materials and methods

Deltaprintr sells 9 carriage wheels with bearings for $20: http://deltaprintr.com/shop/hardware/carriage-wheel/

Graber sells them for $7.45 each, which works out to $67 for a set of 9: http://3d.grabercars.com/?product=dual-623-v-roller

You will also need the usual M3 bolts, washers and nuts:

- 3 M3x25 bolts for the axles.
- 3 M3 washers as spacers.
- 3 M3 nyloc nuts to hold the wheels on.
- 1 M3x35 bolt for pretensioning.
- 1 M3 nyloc nut for pretensioning.
- 2 ball studs.
- 2 M3 nylock nuts to hold the ball studs on.

Contact me if you need an inexpensive source for the ball studs. I had a bunch custom fabricated. 1000 were essentially the same price as 50, so I have lots left over to share with the Delta/Maker community! I'm offering them for $1 each, plus shipping. haydn.huntley@gmail.com
