If you’ve bought the Wind Deflector 3D files from us, there’s a better version sitting behind the same download link you already have — no re-purchase, nothing to click. We also owe some StickFree Yoke Fix owners an apology and a free replacement, we’re seriously considering offering more of our parts as downloads and would like your opinion on it, and there’s now a second way to reach us.

Your Wind Deflector Files Are Already Updated

Here’s the good part first: the download link from your original order always serves the newest version of the files. It isn’t a snapshot of what existed the day you bought. If you still have that email, you already have the current release. Nothing to re-buy, nothing to request.

What actually changed is worth a minute, because the old set had some rough edges that made your printer’s life harder than it needed to be.

The parts now land flat and centred on the build plate. The old files were exported in whatever orientation they happened to be modelled in — one of the bushings sat about 50 mm above the plate, floating in space, and another was tipped at an angle and slightly sunk below it. Any competent slicer can fix that, and most people did without thinking about it. But if you handed the files to a print service, you were relying on someone else to guess how the part was meant to sit. That’s not a thing you should have to hope about.

The two bushings are now one print file instead of two, laid out together, so it’s a single plate rather than two jobs.

And there is now a README in the download. It says supports are required and roughly why, it gives the settings the production parts are actually printed with, and — the bit that prompted all of this — it says which bushing goes where. A customer wrote in recently to say his two bushings had come out the same length when the instructions implied they should differ. They hadn’t, as it turned out. But we were calling them the “8mm” and “5mm” bushings, and 8 mm and 5 mm describe a shoulder height that isn’t the easiest thing to measure on the finished part. Both bushings share the same bore and the same little collar, so if you measured either of those, they looked identical. The listing now gives the outside diameter and the overall height for each, which are the two numbers that actually tell them apart, and the README says the taller one goes to the lower mounting point.

Now the part that’s on us. That update went out in July, and we didn’t tell anybody.

Two things went wrong, and neither is a good excuse. Uploading a new file and announcing a new file turn out to be two separate steps on our end, and we only did the first one. And the announcement, had we sent it, would have reached almost none of you anyway — it was built to email people we had a download record for, and most of you bought before that system existed, so you were invisible to it. Files sat there, improved, for a month, and the people who paid for them had no idea.

Both problems are fixed, everyone who has ever bought the files has been emailed, and everybody now has a working link on record. If you bought the 3D files and never received that notice, something is still wrong on our end — please tell us and we’ll sort it out immediately.

Should More of Our Parts Be Downloads?

That whole episode got us asking a bigger question, and this one we’d genuinely like your input on.

Right now the Wind Deflector files are the only thing we sell as a download. Everything else, you buy as a physical part that we print, inspect and ship. That works, but it means anyone outside the US pays shipping and waits a week for something a printer in their own house could produce in an afternoon.

The obvious candidate to go next is the StickFree Yoke Fix. It’s a small part, it’s popular with people who already own a 3D printer, and there’s no reason the files couldn’t be yours.

We’re not committing to it yet, because we’d rather ask than guess. If you’d buy the StickFree as a download, reply and say so. Equally useful: if there’s a different part of ours you’d rather print yourself, tell us which. And if you think selling files is a bad idea — some of you have strong opinions about where those end up, and we’d like to hear those too.

If Your StickFree Has a Nub, We Owe You a New One

This one is a straightforward apology.

A batch of StickFree Yoke Fixes went out printed from the wrong revision of our file. The bad revision leaves a raised nub on the inner curved surface, right around the mounting screw. It’s small, and it’s easy to miss if you aren’t looking for it — but it obstructs the clamp, so the two halves never seat properly around the yoke shaft. Which is the entire job the part exists to do.

How to check yours: look at the inner curved surface, especially around the mounting screw. It should be completely round and smooth — no bumps, no obstructions. If yours looks right, you’re fine and there’s nothing to do.

If yours is affected, reply and pick whichever suits you:

1. A free replacement — corrected parts, no charge, free shipping, and keep the old set. There’s nothing to return.
2. Fix the one you have — the nub sands or chips off flush without much trouble. PETG-CF cuts easily.
3. A full refund — if you’d rather just have your money back, say the word.

We emailed everyone we could identify back in August, and most of those have already been replaced. This is for anyone we missed, anyone who’s bought since, and anyone who got that email while on holiday and forgot about it. The offer doesn’t expire.

This was our mistake — the wrong design file on our end, and our own inspection didn’t catch it before the parts went into boxes. We’re sorry.

Checkout Now Catches Address Mistakes

Smaller, but it’ll save somebody a headache.

The cart now checks your shipping address before the order goes through, and tells you which specific field is wrong rather than rejecting the whole form and leaving you to hunt for it. It also runs the address past the carrier, and if they know it in a slightly different form — a standardised street abbreviation, a corrected postcode — you get a “did you mean this?” with the correction offered alongside what you typed.

That last part is a suggestion, not a gate. If you know your address is right and the carrier’s database disagrees, you can keep exactly what you entered and the order goes through regardless. But the common case — a transposed postcode, a missing apartment line — now surfaces while you’re still on the page, instead of days later as a parcel that’s gone somewhere unhelpful.

If you’ve ever had a delivery go astray on us, that’s the class of problem this is meant to end.

Thermolink: Still on the Bench

We mentioned Thermolink previously — the smart controller for heat pump and mini-split systems — and said we wouldn’t put a date on it.

We’re still not putting a date on it, and in the interest of not padding this out: there is nothing new to show since the last update. It hasn’t been shelved, it simply hasn’t been the project getting our evenings lately. When there’s something real, you’ll hear about it here first.

Reaching Us

Last thing. Email is far and away the fastest way to get us, and if you use the contact form it lands in the same inbox — so use whichever you prefer. contact@debyltech.com reaches a person, usually the same day.

We’re also a registered WhatsApp Business, on +1 603-416-0859. We’ve been using it with customers for a while but had somehow never mentioned it on the site, which rather defeats the point. If a photo of the problem would explain it faster than three paragraphs would — a part that doesn’t fit, a print that’s gone wrong, a dash showing something odd — that’s often the quickest route.

Either way: if something we made isn’t doing its job, we want to know. We would much rather hear it from you than not.
