I had no problems printing the screw - as some wrote - but it all depends on the printer and quality of bed. Before print I always using antibacterial wipes…
As for me, everything done from PET-G, 80 degrees bed, 230 degrees hotend and most importantly - the speed of 45 mm/s worked perfectly.
If you have a problem with squeezing, try cleaning the syringe needle. This is where the greatest resistance occurs.
The author remixed this model.
Changes made:
- I changed the thickness of the left/right sides. Now the hooks are much more durable.
- I changed the thickness of the lower crossbar, which the syringe rests on.
In the first version it broke. Now it won't happen again
- I changed the pattern on the knob to remove the "hanging" sharp very small triangles on the lower and upper edges. Now the print is easier and cleaner.
- I added a small piston that you can insert into the syringe. This prevents the original piston from tilting.
