Summary

No denying, the carriages on the TLM require a fair amount of adjusting to achieve perfect tension with the added challenge of being equal across all three. I've attempted to take the guesswork out of it by designing an adapter that converts the carriage into a three-wheel configuration, provides consistent tension, and uses existing hardware.

I'm publishing this as a Work in progress so that fellow TLM patrons can help test this with me. Please post comments on your experience and any constructive criticism you may have. Thanks!!

UPDATE-V7
I found the current design actually flexed to the point the posts would rub, so I made them stiff. If you want some flex it might be worth printing in semi-flex or nylon. I will still pursue a design that doesn't require adjustments of the concentric nuts, but at least with a trike the adjustment will be even across the 3 wheels.

UPDATE-V8
I tweaked the over length as it made it rather difficult to get the bolts through. I must've left it long for when I was dabbling with the suspension design. I also increased the height just slightly as I noticed tidbit of bowing when tightened. I don't believe it causes much of an issue but could rub off debris over time. Side note: I uploaded the wrong V8s, they have been corrected.

Notes:

Print with 5 outlines and you won't have infill. I recommend Taulman 910 Nylon. If you use something else, let me know how it turns out!

UPDATE
I've printed these in PETG and they work as well!

Assembly

Carefully remove the three carriages from the printer and disassemble the two stationary wheels on each of them. We want the concentric wheels in place for potential adjustments. This is a great opportunity to inspect the wheels for wear and crunchiness. I recommend picking up some quality replacements (e.g. 3DVice). No additional hardware is necessary and you can use the same Allen wrench and open end wrench from your installation kit.

  1. Insert the Allen bolts through the carriage plate
  2. Squeeze the bottom adapter and slide onto the Allen bolts (like a bow)
  3. Place both brass washers on the bottom adapter post
  4. Place the bearing on the bottom post
  5. Press the locking nuts into the top adapter
  6. Place the top adapter and loosely tighten the bolts to allow some movement for flexing
  7. Adjust the two concentric nuts on the other two wheels to furthest position away from each other.
  8. Rinse and repeat for the remaining carriages

Eccentric concentric nuttiness.

All ready to go; well, after I finish the other two and put the printer together. They should hold their own weight with little effort to slide up and down with absolutely NO bearing crunchiness.

I like this very much! Similar to how the Rostock Max V2 addresses wheel tension on the cheapskate carriages. Great idea! Great work!

Thanks! I was inspired by my RMv2 along with the 3 wheel Tricklaser trucks. It's a rather tight space I have to design around the belt in the middle. I published another update that makes the bar stiff since there's no avoiding the concentric adjustments, for now. I've got some ideas to further the design when time permits.
