GT2 Pulley - the big collection updated

PROJECT HISTORY

Edit 20.4.2023: HUGE UPDATE

I completely remade my parametric model that helps me generate pulleys more easily. As a result:

1. I reuploaded all files with cleaner .stl files.
2. Now smaller pulleys available - some have very thin walls that aren't suitable for 0,4mm nozzle but you could use small nozzle or SLS printing.
3. Added 10 mm shaft diameter.
4. Added version with M3 nuts.
5. Added new collet style that is much more precise, is less prone to wobble and holds much stronger on the shaft but it is suitable only for bigger pulleys.
6. I can much more easily generate different sized pulleys (teeth count, belt width, shaft diameter…) so if you miss any, please let me know what parameters you need and I will upload it.

Edit 15.12.2022: Some more sizes for the 5mm shaft and now also 6mm and 6.35mm shafts.

Edit 12.12.2022: Added more sizes for the 8mm shaft.

Edit 11.12.2022: Added chamfers to the wheels for better printing and prettier design. Also added few more pulleys.

ABOUT

I couldn't find reasonable GT2 pulleys that I needed for upcoming upgrades/projects so I made my own pulley generator and here I give you some pulleys.

• Tooth profile precisely created based on GT2 belt geometry - test yourself.
• Pulleys are designed with 0,1 mm tolerance in shaft diameter - that is great snug fit for me but if you find it too tight just use a drill bit and clear the hole (tighter fit means less wobble in the pulley).
• Use M3 hardware to secure the pulley to shaft - either screw/setscrew or with a nut.
• Standard version with setscrews that “bite” into the shaft.
• More precise version with collet that is less prone to wobble on the shaft, holds more securely and is not affected by threads if you use it for example on leadscrew.

GUIDE TO CHOOSE PROPER FILE:

     GT2_Pulley_36T_8_R_SS.stl

• GT2_Pulley - obvious
• _36T - teeth number
• _8 - shaft diameter in mm
• _R - type of shaft fitting (R=round shaft, D=D-cut - shaft with flat spot)
• _SS - type of securing to the shaft (SS=setscrew, SN=setscrew+nut, CS=collet+screw, CSN=collet+screw+nut)

If you really like the design and/or just want to appreciate my work and time spend, you can buy me a coffee.
