Printer : Print Rite DIY
Rafts : No
Supports : Yes
Resolution : 0.15
Infill : 20 %
Notes : Printed in PLA. Wheels are better if printed in resolution 0.1 mm. Based on axles are 2 STL files. You can choose between M3 Bolts axles or 3 mm diameter rod. I personally prefer the one with bolts, no cutting easier to find, easier assembly. Bolt should be 12-15mm long Rods 30 mm long For magnet connection between wagons I suggest checking solution from this design: http://www.thingiverse.com/thing:2222472 http://www.ebay.co.uk/itm/302243779048 http://www.ebay.co.uk/itm/161327980527
