Rocker Latch for Tineco Vacuum

This is a replacement for the black latch on Tineco Pure ONE S11; on mine, the nubs broke off so the latch would not stay. 

I recommend printing in PETG for strength. You may want to cut off the nubs before you do your first trial fitting, so that you can remove it if it doesn't fit or function well in your particular vacuum. 

Print it slow and hot to improve layer adhesion. My PETG print parameters on a K1 max:

• Bed: 75 C

• Nozzle: 255 C

• Speed: 40 mm/sec

• Fans: 20%

Make sure you print with supports for the nubs and the finger spot (look at the bottom).

This model was created by taking caliper measurements from a working latch, plus some iterative tweaking.  The Fusion 360 file is available if you'd like to see the measurements or alter the model.

This work is permissively licensed. I don't mind what you do with it; I provide no warranty.

I created this model as an alternative to the one located here:

I found the above model was a poor fit - didn't latch correctly and the hole for the spring was too small.

06-Sept-2026: I uploaded Version 2 which has a beefier latch and added fillets to improve strength. I found the first one cracked after a few weeks of regular use.
