TWO TREES® Black 2020 Profile X-axis Synchronous Belt Stretch Straighten Tensioner for 3D Printer
A part of the review has been auto-translated.
ok. works as expected! Maybe a solid aluminium block would give a simpler and cheaper design... thanks BG
Required shortening of the x-axis belt for the correct fitment of the part. Moved the brass ferrule about 10mm in and re-crimped it. Worked perfectly thereafter.
Very good tensioner. Very well made.
Good material and appearance, but poor production calculation, the equipment barely fits the 2020 profile, the drilling has 5mm more than necessary, the second screw has almost no space to tighten.
The length of the tension bolt is short enough to make the stroke, and the designed stroke is not utilized. The photo shows a 40mm bolt, but 35mm seems to be enough.
Good tensioner. It works well on my Ender 3.
looks very good, feels high quality, came out of the box without any issues, the screws to mount them on the profile are standard T slot nuts and mount easily this product makes it really easy to adjust the belt tension, which is the purpose but still, somewhat a must have upgrade for every (especially Cartesian) 3D printer
Good product, not tested.
Excellent upgrade, I had made a printed model however it was crooked and damaging the belt, this model is tailored and features a pulley to guide the belt, different from the original that only uses a bearing. Perfect.
easy to install perfect upgrade for 2020 rail
