This is an improved version of my first blasting machine that improves durability, safety, and accuracy when activating the machine.

As always my design is a remix of https://www.printables.com/model/173169-10-cap-blasting-machine and the credit goes to him.

The good news is that if you've already printed the original design, many parts will transfer over to the new one.

This new design has the top plate built in to the cover and comes in 2 versions: a smooth plate and stencil if using a .4mm nozzle, or detailed plate if printing with a .2mm nozzle.

So here are your options for printing:

If you have already printed off the old design and want to upgrade -

top cover CONVERSION 1 --or-- top cover CONVERSION 1 DETAILED,
top cover CONVERSION 2

If printing new-

top cover CONVERSION 1 --or-- top cover CONVERSION 1 DETAILED,
top cover CONVERSION 2,
top cover handle,
improved base + 9 volt,
body connector(1),
top cover knobs
