So, having taken a slight detour with my Dalek Rhaegal build, I completely forgot about poor old Davros, and that I hadn't finished uploading all my models! So I've spent a bit of time renumbering and cleaning up all my models and have now packaged up all the console structure 3D print parts into one zip file. Pending approval, they should be available in the 3D print files as "SKV-DVA-C002 DAVROS-ASSY CONSOLE STRUCTURE". As there are so many parts, I've done a batch of drawings to accompany them, as otherwise they'd be a nightmare to follow! Printing will take some time, as there are a good 30+ printed parts. I will upload the arm rest separately, as they are quite large files, and I still haven't quite finished the drawings for those yet. I've also attached all the drawings for the panelling, which is made from a mix of 6mm MDF and 3mm hardboard. The 3D print parts slot together with the modelled in locator lugs. Once assembled, there are deliberate gaps around the edges, which are there to allow space for filler so that the edges are cleaner once they are sanded back. Please refer to drawing no. SKV-DKA-C002 (2 sheets) for the full assembly details. 

Thanks for taking the time to explain this - much appreciated.   By 'inner core shape', I presume you mean the lines labelled 'inner shoulder frame - upper outer edge' and 'inner shoulder frame - lower outer edge' on the template. So I cut the upper and lower frames using these lines as the cut marks, reducing the diameter by the thickness of whatever material I use as the base layer cover for the shoulders, which should at its outer diameter be in line with 'B'.   TVM  

Have you tried any other versions of the 555 IC circuit. Without pin 7 and pin 5 connected, could be a bit concerning. From Kevin's many year's with the 555 IC, then I can forsee this may have the potential to be an unstable oscillator. Unless someone else can prove me wrong? The 1 microfarad timing capacitor is wrong for a voice mod. Bet you got some of your info from a Google search. Sure they will recommend 10K to 100K for the timing resistor's and 1uF as the timing capacitor. These components are the standard items to get lower power consumption from the 555.   For a Voice Modulator, the 100uF and the optional 47uF is what Kev use's. Then change the timing resistor's to suit. Stuff the extra power consumption above the standard recommendation's that are listed in the 555 data sheet.    When you have a 555 IC timer circuit that you are happy in, makes all the difference Lad!  

Ok, a few more rows to make up one complete panel, but it's looking so much better! And I don't need to print a full set, a lot of the heronrib in the MK2 neck cage will be usable.     The nice thing is that the spaghetti explosion in the last post is a much rarer occurrence with this printer than the last two. A bad workman may blame his tools, but I also give them credit where due.
