Simple and economical drying box for Prusa spool. This design does not require printing a central cylinder for storing silica gel. The silica gel is stored directly in the spool cavity. The center of the spool is closed with a grid, which is attached to the sides with snap-on clips. These clips hold the grid on the spool very reliably.
Advantages and Disadvantages
+ Fast print with minimal filament consumption
+ Maximized use of internal space for silica gel
+ More air contact with the silica gel
- Work only for Prusa spools
- Less convenient silica gel replacement
Printing Instructions
The model is simple to print but requires high precision to ensure that the side clips reliably hold the core grid. A prop`erly printed clip should be very difficult to detach with just your finger (better to use a screwdriver). Make sure you have a well-adjusted printer and calibrated filaments. I spent a lot of time testing the correct settings and dimensions, so I highly recommend using my provided print profile without significant changes.
The best material for printing snap-on clips is PETG or TPU for AMS (hardness 68D). ASA or PLA can also be used, but I recommend higher quality PLA that is not too brittle, such as Bambu PLA. You can use almost any material to print the central grid.
Notes
When viewing the model, you will see the central core part as a solid circle without a grid. This is normal - the grid will appear after slicing the model (if you use the original print profile).
