triple thred easy lock hanging round containers - easiest threads to print - concept

triple thred easy lock hanging round containers - easiest thread to print

can be uniform scaled (all dimension with same ration on all objects) -I do not recommend going to the extreme because the design can be inefficient
no suport needed

approx parameters.:
diameter of all containers - 62mm
height of both big containers - 73mm
height of small container - 25mm
holes in the holder - 4x 4mm use at least 2 screws diagonally

-easiest thread to print - not very usual 6x external thread (3 external threds on outer and 3 external threads on inner body)with a large pitch angle
-with 3 different options of tolerances for threads.: 0, -0.15mm, -0.25mm, -0.5mm,
-2 toleration option for groove on container hanger.: -0,15mm, -0.25mm
-the maximum need to turn the lid for locking corresponds to 120 degrees from any point around the perimeter of the lid
- the container can be inserted into the holder in 8 different positions around the perimeter (45 degrees each)
-you can screw and unscrew the container from the lid without removing it from the holder
-there should be no problem when printing, it is support-free and does not require any post-processing after printing

including.:
-3 versions of container basic, reinforced and small
- hanger with one groove for attaching 1 container in several variations

print one small container with lid and one hang first try your tolerance - recomended container -0,15 hang -0,25
-0,5 tolerance is ridiculously high tested with 0,8 nozzle the thread was loose but still functional
-if you need this or a larger tolerance range, because of any geometrical errors your printer is definitely not in good condition and probably diverges between the X and Y axes means they are not in right angle (90degrees)

-!!!-extra fit version is challenge print-!!! if you consider the way fdm printers works it should move in small triangles when printing thread and that will cause sharp edges all over thread this edges will go off in first few rotation againts the wall of other thread
these sharp edges are also the same lenght as + toleration on this print so if you sand them away (threads are same lenght so sand outer and inner thread same ammount ) you will archieve the best posible fit
or if you printer is very well maintrained you should be fine with this tolerance to insert inner to outer body of container and rub it againts walls of other thread (you will have to use force to do so basicali you will be sanding the sharp edges away) with this you will get the best toleration possible (this can be done with pla only - other materials like abs/petg need to be sanded)
!!!print extra fit only if you think your printer is one of the best printers around!!!-

note.:
for container holder majority of printers should fit within the -0.25 tolerance option, only the best ones will fit within -0.15
printing a container with a lid is not a problem
if your printer is not in good condition, you could have a problem printing the container holder(it wouldn't fit together right).

Enjoy.!

wall loops .: 2+
infill density.: 15%+
print without supports
recommended.: -0,15 container and -0,25 holder
