I am currently working on replicating the Mothbox Pro as part of the Replicator Team working out of the Machine Agency in the University of Washington’s HCDE department.
I will be documenting the full process here and be giving updates throughout my Mothbox journey!
I parsed though the bill of materials for both the DIY version and submitted an order request for the items I need.
The Mothbox Parts List seems to be up to date and easy to navigate and the total ballpark cost for both the Pro and DIY versions was around 1000$ not including the breakdown of bulk components, the manufactured PBC, and filament for 3D printed parts. This slightly higher cost seems to be due to the increase in price for some of the electrical components.
When ordering, some off the amazon links were out of stock, but I was able to find replacements that work within the schismatics.
I opted for the PB240B1 (24 volt) since the 12 volt version was out of stock but that seems to be a common issue. Looking at the links now, the 12 volt version is currently back in stock.
Once components start to arrive, I will update this post.
I have been using an Elegoo Centauri Carbon for printing the Mothbox Pro case. I used ERYONE Carbon Fiber PETG filament and found that 2 140g spools allowed me to print 2 full Mothbox Pro’s (back lid, front lid, outer shell, and inner shell) as well as an extra inner and outer shell.
The outer shell with supports barely fits within the 260 × 260 mm print volume, but both prints came out exceptionally well.
The back lid, front lid, and inner shell printed successfully without additional supports, while the outer shell has some overhanging geometry the requires support material. I attempted to print the outer shell without supports and it came out a bit messy and needed a lot of cleaning up. It could potentially still be used, but I would be concerned about the seal of the front lid.
I am currently working on dialing in the setting for printing the TPU parts using ERYONE TPU 85A. I’ve never printed with TPU before so my first attempts at prints did not turn out. I have been playing with the temperature, flow rate, speed, and infill amount. I am getting closer with my setting and should have them dialed in soon.
Interesting, the ties look a little short. are you using the latest version of the ties on the github?
I’m guessing the spools were 1kg each, right? do you have odd 140gram spools?
