Otto Diy Vertical Extension

### Description

This stackable spacer gives you 20/30/40 mm of additional height for Otto DIY v9.

e.g. more room for a larger battery

## Please note:

There is a similar design by [jabferrera](https://www.thingiverse.com/jabferrera/about) i.e. [Modulo Crecimiento Otto DIY](https://www.thingiverse.com/thing:2933379) that however seems to be off by about 1-2 mm and was not fitting my [Otto DIY v9](https://www.thingiverse.com/thing:2398231) print.
