Ryobi R18CG Caulking Gun to screw connector adapter

This was designed to make this Temu caulking gun into an extruder for clay and pottery work.

The tube on the Temu gun is longer than the reach of the Ryobi, so I have included a spacer to “reset” and continue once the Ryobi has reached its limit. However, after adding the indent to the spacer bottom, it is about 10mm short of a complete extrusion of the tube.

You will need support for the screw connector print base for the outside wall, using Cura block support for the rest of the project. Printing the connector the other way has its own challenges with the tightness of the connector tabs.

The connector spacer is printed “nut” end down with support, and poking the bolt through pops out the support for the print. 

Printed with PLA, 0.2mm layer height.

Designed in Blender and sliced with Cura, printed on Ender 3 Pro.

• This is not for the latest model Ryobi RCG18, that appears to have a screw attachment, and I don't know if it fits the Temu product.
