I thought that instead of buying an additional box, you could simply print a better one yourself!
My box is not only compatible with the Polydryer, unlike the original box it is also stackable, has an improved closure, a slot for labeled cards and three instead of two differently positioned connections for the PTFE hose. In addition, the plugs for the holes in the Box can simply be stored on the lid. The lid is also compatible with the original box!
Note that there are a few important details that you should be aware of when printing this model. Read the entire description carefully! |
You need:
If you don't want to use the axle in the middle as a spool holder, but the ball-bearing axles on the bottom, you will also need 4 ball bearings 14x8x4mm and two metal axles 8mm thick and 95mm long.
I recommend printing the box from PETG, as the polydryer reaches temperatures that are critical for PLA. PETG is also less susceptible to material creep than PLA. The closure would otherwise lose its tension over time.
You will need a flex filament for the seals and PTFE connectors. This should have a hardness of shore 82a or softer! A harder flex filament could be critical for proper functioning.
The gaskets “Gasket-Lid” and “Gasket-B-Plug-Box” are slightly trapezoidal. The narrower side that lies on the print bed is the visible side.
I've found that the accurate fit of the gasket A of the plug is highly dependent on the flow rate when printing the gasket and the plug. In my tests, a 3% difference in the flow rate was already decisive if the plug was too tight or too loose. You should therefore first print a single gasket and then check whether you need to change the flow rate slightly.
Unfortunately, I haven't yet found a design solution that can compensate for deviations in the flow rate.
Print all models as aligned. The lid can be printed without support, but you should use a large brim. To print the lid without support you have to print a large bridge over 80mm long. I've made a small test object so that you can check whether such bridges are printed properly, whether you should change your settings or whether you want to use supports for a nicer surface. |
For the large window at the front, you will need some clear plastic from a packaging (127x74mm). This is fixed in the box with the corresponding seal. In my case, this plastic is 0.3 mm thick. If you use a different thickness, you can scale and adjust the seal in Z in the slicer.
The lid can also be used with the original box! By changing the lid, the original box becomes stackable, you get the improved closure and two additional options for the PTFE tube. For this purpose you need to print the “Closure-ForOriginalBox”. This is shaped slightly differently. |
The box has a slot at the front for labeling. I've uploaded a plate which you can label with the text tool in the slicer (e.g. Prusaslicer).
The container for the desiccant is simply plugged into the box at its position. The lid should be printed from transparent filament if you are using a desiccant with a color indicator.
I would be delighted to receive feedback in the comments. I've experimented a lot with the accuracy of fit and tolerances (e.g. of the seals) and hope to have found average values that everyone can cope with.
