Vacuum Adaptor for DeWalt D26676-XE Planer (To suit 57mm/2.25" hose) by harmo_hammer

This has two 57mm (or 2.25") variants of my 35mm dust port adaptor for the DeWalt D26676-XE Planer
Full Disclosure: I need beta testers!
I actually designed this on behalf of someone else based on their measurements.... and have not tested these models personally. I've subsequently received other requests, so I've decided to put these models up for people to have a look at. If you try either of these models, please let me know how you go so I can ensure my offerings work for people.
Two different files. Please pick the one that suits you best:
Now there are two versions of this file, and the only difference is the length (depth) of the vacuum end. The first one has a 65mm long taper (great for vacuums with the standard vacuum handle) and one that has a shorter, 48mm long taper (so this suits the typically shorter hose attachments/ends). Naturally tapering the same amount over a shorter distance will have a somewhat more aggressive angle.
Both models work on the same principles as my 35mm model adaptor:
The 57mm or 2.25" hose attachment of the shop vac and planer dust port get inserted to their respective ends of the adaptor.
Now the official internal dimensions of the (circular) vacuum end of the adaptor are:
58mm diameter at the open end, and it tapers down to 57.14mm to ensure a decent seal. Normally I don't put as much taper in as this if I measured the vacuum attachment myself, but the greater range should allow a wider variety of vacuums to work with this adaptor.
The first model was designed to be printed on a colleagues Prusa I3 MK2.5, and he has a love affair with PETG, so I've added those details below. However, you could easily adapt it to PLA, and I think it'd work pretty well. Just keep your infill to be somewhere around the 25-30% as I've found that occasionally I put some stress on my 35mm model if it gets caught on something.
In your preferred slicer of choice:
I'd strongly recommend that you ensure that the wide end of the adaptor faces the bed for best adhesion. I also recommend a brim to further improve the odds of success. While the adaptor walls are 3mm thick, a little extra bed contact area won't harm the project.
Now I've had another look at the tapering from the 57mm end to the dust port, and in a vertical orientation, I think you can get away with not using supports, as the angles aren't too bad, but this may vary depending on your situation and preferences. I trust you can adapt any settings to your particular printing circumstances.
