Dolphin Drybox

A 3D printable drybox for your filament spools. Print right from the drybox. (All STEP files included)Print with PETG only!Will fit all regular spool sizes--Bambu, Sunlu, Jayo, etc. Fits all spools less than 203mm diameter X 70mm width. I really spent a lot of time really dialing the dimensions and tolerances for each feature in this drybox (honestly got a bit obsessive…) printing, tweaking, reprinting, more tweaking. This is the fourth major iteration, and there's likely about 100 hours in those little tweaks and fix its to ensure it's as good as I can make it. I don't want you guys to think this is a low effort spam model. I do feel very confident in the printability and tolerances of this--assuming you use what's in the bill of materials (or equivalent) and PETG as print material due to the compliant latching mechanism (I have not tested any other material).
