Topic: Adjustable Y Idlers - Reprise
A short while ago, mdrVB6 was looking for some adjustable "Y" idler block replacement, and I came up with a set which he printed and apparently is quite happy with.
meanwhile someone posted a simple fix for a problem I never knew was there, but it's quite real: flex in the metal frame, where the blocks are mounted. The tension in the belt is actually tweaking the frame

The fix is simple enough, but I thought I'd give it a try with a different way to solve the problem that also combines the adjustable idler in the design
This new block replaces the stock idler block, and also requires 3 holes in the frame. 2 holes are to be drille, the other one, requires the removal of the pressed-in PEM nut. The total adjustment offered device is 6mm.
What makes this different than the original design, is that it fits in the corner of the frame, and provides the stiffness needed to prevent the aforementioned frame tweaking. The slots on the top and side are there to accommodate the pop rivets the frame is put together with.
Here are some views of the drawing, and a printed sample:
SD3 printer w/too many mods, Printrbot Simple Maker Ed., FormLabs Form 1+
AnyCubic Photon, Shining 3D EinScan-S & Atlas 3D scanners...
...and too much time on my hands.
