I spent the morning designing and prototyping this glue stick cap/nozzle combo that allows you to apply glue more precisely. The aim is to replace expensive glue 'pens' used in English Paper Piecing (https://www.thesprucecrafts.com/how-to-english-paper-piecing-4588714)

From this prototype I've learned that a friction fit isn't strong enough to hold the cap on while dispensing glue. Furthermore, if you try to get around this by holding the cap down, the print fails before the glue comes out.

To remedy the first problem I'm going to try a glue stick with a screw-on cap. The second will require me to abandon the use of vase-mode for the print (boo!) so that I can make the walls thicker.

Have you experimented with layer heigh for vase print?

Also, bigger nozzles would give you thicker prints with vase mode, wouldn't they?

@MaryPot A wider nozzle would let me print thicker walls in vase mode, yes. For reference I'm currently doing 0.8mm thick walls with a 0.4mm nozzle. I have not experimented with changing the later height.

At this point I think that a traditional print will give me the strength more easily. 3 perimeters (doubled up for the inside and outside walls) would be 6 times the surface area between layers. That would be hard to beat using a single wall in vase mode with my setup.
