This adapter will allow you to connect an astronomy type camera with 1.25" nosepiece to a Pentax K mount lens.
The design is for the sensor plane of the camera to be 10mm inside the 1.25" holder, making it ideal for cameras that have a 1.25" profile throughout (ie QHY cameras) or the Altair GPCAM.
If you have a camera where the sensor cannot be placed this far within the 1.25" tube, you will need to alter the design to shorten the tube.
To get a good secure fit, also print the spacer ring which you place between the main adapter and the lens mounting plate. Having a separate spacer ring avoids the need for any supported areas in the print.
