Background
The Top Belt Tensioner designed by Atziano (see "Remixed from" link) is really effective and does the job nicely - but I had real trouble getting the captive nuts to fit properly. This is probably due to my printing technique!
So I redesigned the slider in OpenSCAD to use M3 threaded inserts that I bought from eBay. If you can't get exactly the same inserts you can modify the recesses to fit whatever you can get.
I used M3 nuts drilled out to 3mm as spacers on each side of the belt pulley.
UPDATE: I found that the bearings were noisy in my original design - they rattled around on the M3 screw as they weren't securely fixed. Version 2.1 has a built-in spacer, and uses a M3 nyloc nut to fix the bearing in place. The threaded insert has been removed from the bearing support screw.
Hardware
- M3 threaded inserts: these were made and supplied by a UK eBay trader - your mileage may vary.
- The screws through the slider that support the pulley are M3 x 20mm (I re-used the ones that came from the printer).
- The adjustment screws are M3 x 35mm.
Update
I have added the insert test OpenSCAD file - this is a small piece for testing the fit of the M3 threaded insert.
