I fixed these parts to correct a problem caused by inadequate handling from the delivery person. Parts Required. 4x 3D printed Z wheel carriage 4x Delrin Mini-V Wheel Kit - http://openbuildspartstore.com/delrin-mini-v-wheel-kit/ 8x Mini-V Wheel Precision Shim - http://openbuildspartstore.com/mini-v-wheel-precision-shim/ 4x 6mm Eccentric Spacer - http://openbuildspartstore.com/eccentric-spacer/ 12x Nylon Insert Hex Locknut M5 - http://openbuildspartstore.com/nylon-insert-hex-locknut-m5/ 12x Low-Profile Screws M5 - http://openbuildspartstore.com/low-profile-screws-m5/ 8x Precision Shim 10x5x1mm (M5 washer works too) - http://openbuildspartstore.com/precision-shim-10x5x1mm/ 4x M6 Washers like these: https://www.amazon.com/Steel-Washer-Plated-Finish-Metric/dp/B009OK4VLQ Assembly: Remove the wheels from the cart and take it off the Z stage. Insert one 6mm eccentric spacer into each carriage. Screw the new carriages to the carts with M5x30mm screws, making sure they are securely tightened. Wheels are now held in place by nuts. Wheel Installation: Place a copper spacer first, followed by the wheel and then a precision shim (or an M5 washer works). Last, add the nut and hold the bolt with an Allen key so it doesn't loosen. Put the carriages back on the Z stage without tightening the bolts yet. Now for the Mini Wheels: Add an M6 washer to the M5x30mm bolt, then put it in through the hole a step at a time. Next, add a mini-V wheel precision shim, followed by the wheel and another mini-V wheel precision shim. Tighten up the eccentric spacers to hold the wheels firmly but not too tightly – you should be able to spin them with slight resistance. Finally, tighten the carriages to the Z stage. I recommend re-leveling and re-tightening the Z belts at this time.
