Trailer lift

Hello. 

Here is a trailer lift for TRX-4M as already been seen and done, this one however is a bit more heavy-duty shaped around axis.

First version is regular, for use with standard trailer wheel and screw. You need to provide another set of screws to secure the lift on the trailer. This allows you to fit TRX-4M offroad (bigger) tires on the trailer rim.

Second version (..trailer lift axle) is built to be assembled with the TRX-4M front stub axle.    You have to provide your own #9753 or #9753X axle and pin, then you can put on any wheel with provided printable 7mm hex (6mm length) and even secure it with printable wheel nut. This assembly is designed to rotate without bushings / bearings, I am currently testing it w/o grease to see the amount of wear. 

UPDATE 06/2025 - The wear is almost nonexistent (on PLA part), there is occasional slight squeeking during high speeds. Still w/o grease. Nothing broke.

 On a side note: the trailer construction is not suitable for higher speeds (walking speed forest trailing) even with softer tires (stock canyon trails) as it jumps around a lot - its too light. I put in some “luggage” but it still needs more weight, perhaps 2 spare batteries :)

Thank you.
