Thats a nice one! Couldn't you put the lock rings in the inside so there would be no need for longer rods?

I guess it should be possible if you can find lock rings with a small enough diameter so that they don't touch the bearing clamps on the other rod.

You will also have to create bearing clamps with a larger inner diameter so that the lock ring touches the bearing.

By putting the lock rings inside you'll loose the advantage of keeping the panels tight together though.

Do not forget to put grease on the balls of the ballplunger !


I think I found out what happens if you forget to renew the grease. I have had 3 cases of the piece behind the nut (for want of a better description) breaking off, leaving the nut exposed and the eventually falling out together with the ball-plunger. It could also be that I tightened the ball plungers too tight. I used PLA with 100% infill, maybe it's too brittle. Fortunately I had a spare when the first one broke so I could replace the broken one. Then I immediately printed a few spares.

Anyone else seen this? I quite liked the solution actually.

I am going to try Karl's suggestion - I ordered the parts a few weeks ago but never got round to installing them. Today the 3rd end cap failed so I'll at least replace that rod, maybe all of them
