This is a remix of Hayden Huntley's 2020 Carriages for Zero-Backlash Magnetic Arms https://www.thingiverse.com/thing:2183347. I wanted a carriage to be mounted on the Openbuilds V-Slot Gantry 20mm plate.
Here is a list of materials I used:
Parts for one carriage:
3 pieces of Xtreme Solid V Wheel™ Kit, http://openbuildspartstore.com/xtreme-solid-v-wheel-kit/
2 pieces of M5 x 6mm spacers, http://openbuildspartstore.com/aluminum-spacers
1 of the M5 x 6mm eccentric spacers, http://openbuildspartstore.com/eccentric-spacer/
1 of the V-Slot Gantry Plate 20mm, http://openbuildspartstore.com/v-slot-gantry-plate-20mm/
3 M5 x 25mm button head bolts for three axles.
2 M5 x 16mm button head bolts to secure the carriage to the gantry plate.
7 M5 flat washers.
5 M5 nylon lock nuts for three axles and two for securing the carriage to the gantry plate .
2 3/8" ball studs from Hayden Huntley http://www.MagBallArms.com.
4 M3 nylock nuts, 2 to secure the ball studs, one for securing the G2 belt to the vertical post and one to secure the upper G2 belt.
4 M3 flat whashers, two for the M3 x 40mm bolts, one to go under the M3 nylon lock that secures the G2 belt to the vertical post, one to go under the M3 nylon lock nut that secures the upper G2 belt.
2 M3 x 40mm hex bolt for the tightener.
1 M3 x 12mm hex bolt for securing the upper G2 belt.
1 M3 x 20mm flat head for the vertical post G2 belt attachment.
1 M3 16mm hex or button head bolt for End stop adjusting (optional).
5 M3 nuts, 2 for the G2 belt tightener, 1 to secure the vertical post to the carriage, one to be inserted in the slot near the top of the carriage for the end stop adjusting bolt and one to lock down the end stop adjusting bolt (see the pictures).
For strength I used 'Fast Honeycomb' for the infill.
The lock nuts for the 3/8" ball studs have 8.5mm holes to insert a nut driver to help secure the nylon lock nuts.
