Mine was looking worse for wear and being held together with tie-wraps so had a go making this as a one piece item.. Printed in ABS (more durable for outside use I believe). Use only touching bed support for hose connector or your printer may fill internal holes which will be difficult if not impossible to remove The holes for the tie wraps should hold them in place but not be so tight as they cannot be adjusted as they wear against the sprocket. They are sacrificial and are supposed to touch sprocket at all times.
