August 12, 20205 yr Hi All Do you own a KT-LCD2, KT-LCD3, KT-LCD6, KT-LCD8 or KT-LCD10 display with a broken button assembly mounting bracket? I have a small number of replacement mounts to give away, all costs covered (UK only). The repair doesn't involve any glue or adhesive and is secured using the existing screw & nut. All I ask in return, is for your feedback on the installation, fitting and efficacy of the replacement mount. If you are interested, please let me know. Dan Edited August 12, 20205 yr by danielrlee

Dan I am interested, but for a different system, but the same problem. Could I see a picture? regards Andy
August 12, 20205 yr Author I am interested, but for a different system, but the same problem. Could I see a picture? regards Andy Sure, here's a couple of photos of the mount: I don't have a photo of the mount attached to the button assembly, since I do not currently have a broken one to hand. The fitting profile has been tested and mates well with the button assembly. This mount has been designed specifically for the above displays, so won't work on others unless they use the same button assembly. Which model of display is yours?
August 12, 20205 yr Sure, here's a couple of photos of the mount: [ATTACH type=full" alt="37718]37718[/ATTACH] [ATTACH type=full" alt="37719]37719[/ATTACH] I don't have a photo of the mount attached to the button assembly, since I do not currently have a broken one to hand.

August 12, 20205 yr Which model of display do you have? Its actually the push buttons to control certain features on my bike, on and off being the important ones, and PAS steps. I have no idea who manufactures it, and as far as I am aware, the model is only sold with the bike I own, but I am not 100% sure about that.....it is separate to the display, on a cable. I will simply use a high quality glue (2 part for plastic) to attach them to each other.... regards Andy
August 12, 20205 yr Nicely 3D printed Daniel. I would suggest making the material at the bottom of the clamp a little thicker and put in a recess for a captive nut for the tightening bolt, that way you only need to tighten it from one side and don't need a spanner and screw driver at the same time. What material are you using, PLA?

What material are you using, PLA? The button assembly itself holds the nut captive, so one is not required on this part. The part pictured in the above photos is printed with PLA, which has proved sufficient for all clamps I have printed previously. The only time I ever use PETG is when a higher glass temperature is required. I used to use a fair amount of PETG whenever I needed something a bit tougher, but modern PLA is much improved in this regard, so I rarely bother anymore.

August 12, 20205 yr Author May I try that out? Andy Sorry Andy, It would be absolutely pointless. This part relies on the structure of the existing button assembly and is perfectly aligned with the existing captive nut and screw, which it uses to create the required tension in order to hold it all together. You'd be better off epoxying a jubilee clip to your button assembly.
August 12, 20205 yr Would this fit an LCD8H? My existing bodge of superglueing a zip tie to the button box has finally given up!
August 12, 20205 yr Daniel both of my button pads have snapped for LCD2 & LCD3. The 2 I'm not to bothered about as it is fairly tight still but the 3 is a loose as anything, so wouldn't mind one please.

Dan Hi Dan if you still have any left i would appreciate one for the lcd3 mine is broke on the bend that the bolt goes through.
August 12, 20205 yr Author Hi Dan if you still have any left i would appreciate one for the lcd3 mine is broke on the bend that the bolt goes through. [ATTACH alt=lcd3 switch.jpg]37734[/ATTACH] Yep. You'll have to remove the remaining portion of the bracket to make room for the replacement though. Just PM'd you.
August 12, 20205 yr Yep. You'll have to remove the remaining portion of the bracket to make room for the replacement though. Just PM'd you. No problem i'll cut that off and thanks for letting me have one.

The only time I ever use PETG is when a higher glass temperature is required. I used to use a fair amount of PETG whenever I needed something a bit tougher, but modern PLA is much improved in this regard, so I rarely bother anymore. I see, so the nut is held captive already in the switch. I would probably still put a little fillet into the area in blue, to avoid stress concentrations at this critical point: Modern PLA is pretty good, I've made quite a few bike attachment parts from it. It's usually fine so long as you don't hit it hard with a hammer. But this design should be fine in terms of toughness because of the orientation of the layers and there is no space filling.
August 13, 20205 yr Author I would probably still put a little fillet into the area in blue, to avoid stress concentrations at this critical point: Good suggestion, thanks. There should be room for a small fillet there if I leave a cutout for the screw head.
August 13, 20205 yr Good suggestion, thanks. There should be room for a small fillet there if I leave a cutout for the screw head. Have you thought of providing a general 3D printing service to people on the forum? There are loads of areas where it would be a big help to people. There are all sorts of clamps etc you could make for people. For example, battery mounts that are secure and don't risk damage to bottle holder bolts: Or controller mounts: Small components, like this gear tensioner bracket, so the Powabyke could use modern indexing gears: Not to mention all sorts of brackets and clamps to fit things onto handlebars...

Yes, it's something I have considered, but decided it would be too time intensive due to the wide variation of component and frame dimensions and therefore prohibitively expensive. Anything involving one-off fabrication is not of interest to me as a commercial operation. There are already 100's of UK based 3D printing companies that will simply print an STL if forum members require such a service. The only exception I would consider is high-end fabrication, where one-off costs are easier to recoup. Edited August 13, 20205 yr by danielrlee
