If you don't care about the “why,” skip this paragraph. I know that it seems counterintuitive that I would have created this model as a means to ENHANCE security, but here's the use case; cash registers were being utilized basically just to store and organize money without being tied to a point-of-sale system, so the keys were being utilized (i.e. left in the keyhole) in a high-volume, outdoor venue for a temporary event. Since these keys work for the cash drawers in permanent locations, I figured that leaving these keys where they could be snatched, or even photographed, was more of a concern than one cash drawer being raided and that money lost, as it's way more expensive and time-consuming to have to replace dozens of lock mechanisms on the existing POS locations if a key is out of our control (or even knowledge of what the key code is, in the case of a photographed key).
Anyway, about the model: I won't get into what brand(s) this will work for, because I'm sure it varies even among models within the same brand. I found that the same design worked for two completely different brands that we have here, so the lock mechanism might be some common industry standard thing, so I'll give some measurements and you can decide if they will work for your application:
- Cylinder Width - 18.5mm
- Width at Flattened Spot - 16.5mm
- Width at Retention Grooves - 16mm
- Depth from Collar to First Retention Groove (i.e. thickness of material) - 1.25mm
- Depth from Collar to Second Retention Groove (i.e. thickness of material) - 3.5mm
- Retention Groove Width - 1.25mm
- Latch Engagement Range (distance from collar) - 11mm-15mm
- Collar Diameter - 25mm
- Overall Knob Size - 29mm at wings
This model prints in three pieces and there is a pin hole that you can insert a piece of 1.75mm filament to hold it in place, though the friction fit is likely enough. I printed these in both PLA and PETG, and both materials held up to way more abuse than people were wagering (myself included). For reference, these were used basically non-stop for about four hours each event, one day a week for 16 weeks and we had no issues (between 6-8 units used at each event); they far surpassed my durability expectations.
