SARIS H1, H2, H3 Bike Trainer Ball Rocker Plate
Print Profile(3)
Description
Rocker plate feet designed to fit a SARIS H1, H2 or H3 cycling trainer. This gives a softer and more realistic feel to riding on the trainer indoors and provides some bounce.
** Version 1.2 Update ** - Front Holder added to add support to the front-middle of the trainer body.
Two versions were created;
Two tennis balls per side which provides a lower profile overall and more distribution of weight over multiple balls per side. This does put more pressure on 3d printed parts, but I have not had issues yet in strength.
A single ball on each side version provides a more direct mount above the ball that simplifies the print and overall system with less force on the 3d printed parts. This has a higher profile off of the ground.
This is designed to use the existing feet that screw into the legs on each side. To mount to the SARIS, unscrew the side feet and put the feet back in through the printed rocker. This doesn't need to be screwed in very far, a few revolutions is enough. Tighten with the lock screw on each foot to lock it in. The rear rocker stand just sets onto the back of the trainer.
Front Holder - Based on feedback, I added a 4th support that fits on the front middle of the trainer body between the two legs. While I haven't had issues with the leg supports, this optional part should lessen the forces on the legs themselves and the printed support pieces. Height on this part designed to match the double-ball / shorter option. See pictures that show the white color part.
Recommend printing with PETG for Leg supports and Rear holder for additional strength. May work ok in PLA as well.
Optional Front holder does not need to be especially strong and I have been using with PLA and only 10% infill with no issues to save some filament.
Front Wheel Riser - I recommend to use a front wheel riser with either of these, adjusted to match the an appropriate height. This one has some default height options and can also be stretched in the Z direction to vary the fit.

If anyone uses this and has feedback, please let me know! Would love to hear how it works or any improvements that could be made.
