**** Update 25.02.2026 **** (1) Added BOM for hardware (2) Updated point 5 of description with my new observations - humidity levels are even better then I initially though

**** Update 08.02.2026 **** (1) Laser CUT template for plexiglass attached (2) Fusion file attached to modify and develop your own modules.

SideBox is a Snapmaker U1 filament dry box design with following key benefits:

1. Easy mounting - No need to remove the spool holders like in other models, no risk to brake them
2. Two mounting techniques - silicone or double sided tape, both are removable from plastics
3. Lightweight - one SideBox adds only around 500g to the weight of the printer
4. Two  versions - single material and multi-material with embedded TPU seal
5. Very effective - I easily managed to achieve very low humidity, same as inside AMS units - both versions “double sided tape+no seal” and “silicon+TPU seal” hold the same low humidity (but with silicone mounting technique and TPU seal version desiccant will deteriorate slower)
6. Well vented - to make sure the vents on the right side of the printer can operate
7. MODULAR - side elements like filament channels, vent modules, sensor modules can be interchanged
8. Expandable - you can create your own modules, Fusion file with modules available in CAD files, feel free to attach your modules as additional print profiles here (describe it please)
9. Easy assembly - hexagonal shape makes multiple assembly and mounting steps easier
10. Very good visibility inside

IMPORTANT: In STL/CAD files you will find Snapmaker Orca 3MF. In print profiles you will find profiles  for H* series. Separate profiles are prepared for main housing (two versions) and the modules. You can print main Housing on U1 of course, on H* series, and other larger printers. However it is too large for 256x256 plates.

BOM (Hardware only) for ONE SideBox

• 3x20mm self tapping screws, 10pcs (for housing)
• 5x2mm neodymium magnets, 18pcs (for housing)
• 2,5x6mm self tapping screws, 32pcs (for modules)
• 8x3 neodymium magnets, 18pcs (for the lid)
• 3/4mm thick Acrylic/Polycarbonate glass 470x250.5mm (+/- 0.5mm) for manual cutting (for laser cutting - template is attached)
• Round humidity sensor (not obligatory, you can use a blank module instead)
