The story behind:
I used Jojo Mayor\u2019s design Perfect Balance to recreate this pedal. All the inspiration was taken from Sonor\u2019s pedal, please make sure you check it out!
Many details are derived, though I had to come up with a new pillar design, suitable for 3d printing. As you can see, it is split into six parts, printed in way, that ensures strength and minimal layer strain.
The rotating mechanisms of hoop clamp and footboard had to be replaced with a compliant mechanism (which I do recommend printing in PETG). Unfortunately, footboard compliant joint does not appear to be very long lasting, so you would probably have to change it.

Recommendations: Before printing all the details, make sure your shafts, bearings, nuts and screws fit clearance_test part. The holes for the screws are a bit larger so that you can freely insert them. Keep in mind, that clearance_part should be printed with pretty the same layer height as in your other parts: making it bigger will result in decreasing diameter of holes. Still, large parts, such as stiffeners, heel_plate, pillar_p1 etc. may be printed with 0.28mm layer height. For other details 0.2mm is recommended.

Make sure you use supports for these parts:
1. pillar_hoop_p1
2. hoop_clamp_p2
3. pillar_p2
4. beater_holder

All the stl's are in printing orientation! No need to rotate them!

Things you will need to purchase:
1. Shaft, 140mm, 8mm in diameter (preferably a steel one)
2. Shaft, 310mm, 6mm diameter, 2 pieces
3. Shaft, 250mm, 6mm diameter, 2 pieces
4. M2 screw, 20mm, 1 piece
5. M2 nut, 1 piece
6. M4 screws, 15mm, 11 pieces
7. M4 screws, 20mm, 8 pieces
8. M4 screws, 30mm, 4 pieces
9. M4 screws, 40mm, 2 pieces
10. M4 nuts, 28 pieces
11. Bearings, 2x, 8mm inner diameter, 22.5 outer diameter
12. Spring or rubberband (preferably first option)
13. M5 hook
14. M5 hook nut
15. 3d printer belt, 6mm
16. Chopstick, 1x
17. Superglue (optional)

If you are not satisfied with direction of pedal, you may mirror parts from this list:
1. beater_holder
2. hoop_clamp_p2
3. pillar_hoop_p1
4. pillar_hoop_p2
5. pillar_p1
6. pillar_p2
7. stiffener_2

Attention! This is not a professional drum pedal!
