Hunter Douglas Applause LiteRise Blind Handle

A handle for raising and lowering Hunter-Douglas Applause LiteRise blinds. May work for other LiteRise blinds, I guess? I'm only really familiar with this particular set of blinds.

This is one of the first models I ever designed, and as such it's extremely basic. In particular, there's a place where a circular arc meets a rectangular section and the corner is sharper than is ideal for hands; if I were making it today I'd have put a fillet or chamfer there. (Because of the print orientation, a chamfer would make slightly more sense on the bed side, and for symmetry's sake…anyway.) That said, it's nice enough to use that I haven't bothered redesigning it after several years, so it's probably good enough. I might have done that if I'd made this in Fusion 360, but I made it in FreeCAD before switching to Fusion, so it's not quite as trivial to add the revision.

I printed this in PETG, and I recommend that, as it's less brittle than PLA. ABS or ASA would probably also be fine. I didn't bother with anything opaque or UV-resistant since mine are blackout blinds, but choose your filament to suit your circumstances.  It's designed to be printed on one end, so that the stresses when the model flexes are within the layers; if you have any concerns about bed adhesion, print it with a brim. I believe I printed it without one, though.

It takes a fair bit of force to get it to attach to the blind, but once it's on, it's not going anywhere. I've had two of these installed for…I guess it's seven years now? They're still going strong. I significantly prefer them over the OEM ones that were on the blinds when I moved in.

The guy at my local blind repair store admired them. He's made some for another brand of blind, and he recommends printing them with “fuzzy skin” turned on to give them a little more grip. I like them the way they are without it (I find the layer lines give it actually kind of a pleasing feel) but it's something to consider.

Please let me know if you wind up using these. I like 'em, but I only recently realized I never got around to uploading them.
