RECESSING TEMPLATE FOR PLACO WALL DIAMETER 67mm

This object consists of helping to drill three consecutive holes with a hole saw of diameter 67mm.  This avoids alignment problems between each hole whether vertical or horizontal.

The two rectangular holes that you see are used to place 2 bubbles at a circular level measuring 35*8. The bubble levels can be found on aliexpress : https://a.aliexpress.com/_EQUpMJB

I am going to make a smaller version for small printer formats because I did not realize the size for the different trays that exists during manufacturing.

Sorry for my approximate English.
