Description
This is a set of 3 hydraulic ram tubes for the ZMX Toy Excavator, otherwise called the ZMX Radio Control Excavator with Steam 2.4G or ZMX Engineering Excavator Toy with Remote Control. This is just the tubes of the cosmetic hydraulic rams, I'll get to the ram rods soon.
Files include:
ZMX Excavator Longest Ram Tube - Middle ram on arm
ZMX Excavator Medium Ram Tube - Lower Cab-side ram on arm
ZMX Excavator Shortest Ram Tube - Upper ram closest to the bucket
And a PrusaSlicer project file
I'd recommend PETG, 100% infill, put a support blocker (cylinder) into the tube where the rod will go. Add a brim and add snug supports elsewhere.
Be advised. I had a hook version but it kept failing. This version has a complete enclosed circular end, you need to pop off 2 or 3 screws on the arm to fit the ram tubes correctly but it leads to a stronger, better experience for your young one.
