Tension Meter for the GT2 belts of i3 MK3S+ or Prusa MINI+
The model of the tension meter helps you control the tension on the belt of your Prusa printer.

I'd probably prefer an STL file and instructions on how to print it, rather than just a fixed gcode...
@baty85 Hey How do you print the g-code. I only deal with STL. Please help!:) Oh and can I use them on a CoreOne?
Hi, I downloaded the G-code for the MK4, copied it to the COREONE, and started printing. The printer said it was an incompatible file, so I clicked through that warning and it printed just fine. I think it should work—the belts should be the same. I printed two copies right away, because adjusting one belt changes the tension on the other one too, so I could see both at once and didn’t have to keep moving the tension meter from one belt to the other...
Printed the MK4 version on my MK4S, printer complained about compatibility but I went ahead with it and it seems to have come out okay. Had used the belt tuner app on the Mini to set tensions right in the middle, and this confirmed.
I did clip the peg on one of the measuring arms because it made it much easier to install. Doesn't make any difference to measuring accuracy, just make sure it's fully seated and parallel to the belt.
Like I said in a previous comment, it would be nice to have the gcodes available for the currently available printers like the MK4S, Core One (and L) and XL.
The most current printer supported is the MK4. No MK4S, no XL, no Core One. Any chance someone can upload the gcodes for the currently available printers?
Works brilliantly! I used Polymaker PolyLite PETG and it still tensions really well.
Don't use black like me though, it's really hard to decipher the text/lines, especially in an unlit enclosure.
Could you public a STL or 3MF file please? I would like to optimize the tool for my MK4S with HF-noozle. Many thanks ;o)
@HREX_106329 from the description:
"We offer g-codes only. It is because the print settings cannot be changed to keep the meter working properly."
Would be nice if they had gcodes to support all the current printers, though.
I used it in combination with the tuner app to make sure I get my belt tension right. Works well!
Only the gcode was provided, which is bad. I printed it from PETG prusament, had to reduce the nozzle temperature to 230°C to prevent stringing.
