Parallel wheels assembly

Proceed in the same way as for the wheels of the cart, but instead of 2 pcs of M6 x 20mm screws, use 2 pcs of M6 x 60mm screws - according to the attached drawing. When assembling the plexiglass cover, screw in the inner nut to hold the plexiglass approx. 15 mm from the end of the screw. Place the plexiglass protective cover on the M6x60 screws. The screws must go through the holes in the Plexiglas cover so that the wider part of the Plexiglas faces upwards. Place the M6 ​​outer nyloc nuts on both M6x60 screws so that they are in line with the end of the screw after tightening. Gently tighten the inner nylon nuts with a 10 mm spanner so that the Plexiglas protector is firmly tightened.
