Intro

This is my newest version of my front wheel raiser for cycling on an indoor trainer.

My main goals, I wanted to achieve, for this are:

  • get the bike level because I have also raised my trainer with a Tennisball mount

  • as I use Tennisballs on my trainer, for the feel, I wanted the same feel also on the front wheel

  • special to this version I wanted to remove any support requirement, as some seem to print my older versions in vertical orientation, which I don't think is optimal, just to don't use support, as this could lead to much easier snapping of the part, because of layer orientation

  • differents to my old version

    • mounted on 4 instead of 3 balls

    • wheel is now centered on the raiser

Special Notes:

  • I highly advise to lock your front brake or use any other way to protect your wheel from rotating, otherwise it will rotate of the raiser!

    • as shown on one of my pictures, I used a velcro cable tie, easy to apply and to remove

  • Also in my pictures I don't show the raiser_tpu_ball_holder, as I use a silicon mat, as I only use my trainer for endurance rides, because of this I never had any issues that the wheel slipped of the raiser

Filaments:

  • PETG - for the main body

  • (optional) TPU (60A or 70A) - for raiser_tpu_ball_holder, it needs to be grippy to hold the balls in position

Printed Parts:

Special Print Instructions:
  •  raiser_4ball_(xxx)

    •  PETG

      • use strong infill pattern, e.g. Gyroid - 10%-20%

      • layer height depends on your nozzle, I would suggest:

        • 0.4mm nozzle - 0.28mm layer height

        • 0.6mm nozzle - 0.32mm layer height

      • support (for cosmetic only)

        • enable support on build plate

        • set overhang threshold to 30%

        • support style: snug
