Summary

WORK IN PROGRESS: This thing doesn't work very well as a pingpong paddle yet. I'm going to make some revisions. I suggest you wait before printing it.

While not the regulation 85% wood, this will certainly up the nerd quotient at your tech company's rec room.

I've printed this successfully and played ping pong with it so I have taken off the "Work in progress" label, but I am still revising: The handle is too long and not tapered enough. I will also be adding a recessed area for a label-maker name tag.

The requirements for net gauges

All net gauges may have a height of about 180 mm. Their width shall be less than 48 mm (heavy
gauges) and less than 42 mm (light gauges) but slimmer is better. Their thickness shall be 2.0mm so
that they can be used for determining the extension of the racket covering up to or beyond the edges
of the blade as recommended in HMO 7.1.1. As net gauges can also be used for the detection of glossy
surfaces at an angle of about 45°, their background may be dark and letters or logos may be white.
There are no rules for advertisements on the net gauges, other than the ITTF logo shall only be
used for net gauges that have been approved by the ITTF. Along one of its edges the net gauge
shall have a ruler of 15cm scaled in mm so that it may serve for measurements as the height of the
cushions of wheelchairs. Figures 3 & 4 draw basic shapes for net gauges used at ITTF tournaments.
Other features may be added but may not change a basic requirement as described in Table 1 and in
the text.

The design of a net gauge shall allow it to hang vertically on a cord. If it does not, the centre of gravity
of its plane is located outside its medium vertical axis, which may lead to incorrect measurements
because the lower part of the gauge will touch the net. For the same reason, the central split may not
be narrower than 7 mm.

On one side the net gauge shall have an incision of 4.0 mm with a tolerance of +/- 0.05mm, and on
the other side it may have an incision of 2.0mm with a tolerance of +/- 0.05mm. The angles of the
projecting part at the top of the incisions must be 90° exactly and rounding on the outside or inside
corners is strictly prohibited. The height of the lateral incisions shall not be less than 152.5 mm, so
that both long edges can be used for flatness checks. All relevant dimensions shall be properly
indicated on the gauge.

Would play completely different from the usual ball but for funzies, never break anther ball ever.

I've seen video of this somewhere. It's a flexible ball.
