I recently purchased a Polyphemus filament drier and found that getting filament into/out of it was a bit ‘clunky' especially in comparison to my RepBox. However, the RepBox didn't provide filament drying or humidity control. 

While looking at both the Polyphemus and the RepBox side-by-side, I noticed that they are somewhat similar in size and from there this idea was born.

Since I don't have a way to (cleanly) cut acrylic, I ended up modeling completely new bottom panels to replace the original ones. This mashup is completely ‘bolt-on’ with no permanent modifications required for either the RepBox or the Polyphemus (although substantial disassembly of the RepBox is required).

 

Parts List: (Screw Quantities revised - I realized that the screws that go through two layers of acrylic need to be longer.)

Qty. 43 = Heatset inserts: (designed for ‘Voron’ M3x5x4 inserts 

Qty. 36 = M3 x 10mm

Qty. 7 = M3 x 16mm

 

Notes: 

  • Somehow I managed to incorrectly measure the leg length and they ended up slightly short when the RepBox is placed over the Polyphemus. I solved this with self-adhesive felt ‘feet’ (the type that is commonly sold as floor protectors for chair/table legs).
  • The bolt sizes are highly approximate - I used a mixture and the holes are sized to provide a good amount of flexibility on length.
  • If using the fan mounts, a bit longer bolt is helpful (~16mm or so).
  • The RepBox pictured is v2.3.1. I am not sure how much change there is between RepBox versions, so this may or may not work on other versions. (I have a v2.1 that appears to have similar mounting points, but I haven't disassembled it to confirm.)
  • The parts are relatively large - I printed them on a Prusa XL. Smaller printers will likely need to split some of the parts up for printing.
  • Yes, I appear to have gone overboard with the heatset inserts, but a heatset insert press really makes it easy to install them.)
  • The .f3d file is included but it is quite messy - I am far from a Fusion360 expert and my timeline shows that clearly. My sincere apologies.
