Summary

I'd rather watch videos on my iPad than stare at a blank wall while running on the treadmill at home!

Instructions

The STL files are designed specifically for the TRUE Fitness Z5 series treadmill. You can modify the clamps in blender to fit different treadmills.

This stand is too big to print in one shot using a MakerBot Replicator.

So, there are several pieces that fit into each other (see pictures):

Left half of the stand (10 hours to print)
Right half of the stand (10 hours to print)
Left clamp (3 hours to print)
Middle clamp (1.5 hours to print)
Right clamp (3 hours to print)

Print settings:

5% infill
layer height: 0.34
number of shells: 1
speed while extruding 80
speed while traveling: 150
turn on acceleration
YES to raft and support material for overhangs

Printable and ready to work. It could use a little bit of improvement so that the pieces fit better. Currently the pieces fit together well, but you can see the plastic starts cracking a little bit. This is does not degrade the stability of the stand, as it still holds the iPad just fine and should not break. It's really sturdy!

I used ABS plastic. Have not tried PLA yet.

Note: The left stand might not print correctly. The slot where the iPad fits might accidentally get filled by plastic with the currently uploaded S3G file. I had to use a saw to cut off part of the left stand, re-print a replacement piece, and glue it on. (the replacement piece is uploaded as LeftSlotReplace.s3g).

If I figure out how to fix this print issue, I will re-upload a better version.
