Bed Leveller Mini Kossel / Delta RichRap

My first upload is now live, so please dive in and share your feedback! I've just received my very first 3D printed item, courtesy of an extremely helpful individual from Oxfordshire (a big shout-out to Greg!). With some careful guidance from him, I spent several weeks assembling the device with a mix of assistance from Greg. However, I couldn't help but fine-tune the build process myself. As soon as it was put together, my first-ever print without support turned out beautifully - just over three hours to finish it up, watching the whole thing unfold! My initial goal was to figure out the primary issue with bed levelling. Having extensively scoured the online forums, sought input from multiple people and dedicated a lot of time thinking about it, I came to the realization that crafting my own manual adjustment method using basic nuts and screws would be the way to go. At first glance, this seemed like an easy project - until reality hit, and redesigns upon tweaks began pouring in! What did I learn? How essential are tolerances when 3D printing with a specific printer model. And oh man, did I desperately need bed levelling - you know, the type that doesn't let you smile, unlike those super-efficient setups? Let's move on to something more useful - the manual setup guide I've provided is self-explanatory for anyone interested in duplicating this solution. Here are the basic parts you'll require: * Sets of 3 M5x50mm Machine screw (cap head, button head or even Pan Head will suffice) * 12 x M5 washers * 9 x M5 half washer * A spring, which is relatively easy to source: find a retractable pen spring with an internal bore of at least 5.5mm. It won't be too tricky - don't worry if it doesn't seem to make sense just yet. Instructions: Drill the existing three wholes on your glass bed using clearance holes about 153.5mm apart, then adjust accordingly as necessary (in case they're missing). Otherwise, calculate the distance between these points and a simple drawing can be plotted up. This will guide you to create the required holes within an approximate perimeter of 16mm from the edges. For this procedure: 1\. Start by positioning an M5 washer on your machine screw, followed by carefully sliding it into the lower bed area. Don't force anything! 2\. After this initial insertion, put in a couple more: another washer, and then insert half-nut followed by one more, ensuring all three threaded rods stick upwards with great confidence - tightly. 3\. For optimal smoothness, get a second nut for one screw thread with a bit of an angle twist using two more M5 machine screws threaded tightly into its opposite sides until only slightly below the surface before applying the first touch. Next, give both of them enough space where nothing would protrude or collide later - just remember they must sit inside exactly as drawn. To achieve optimal adjuster performance, thread an M5 machine screw followed by M5 nut, which can then have washer stuck underneath - ensuring all this gets in perfectly with zero wobble potential; the main issue here isn't just threading everything into a line; instead focusing on creating equal forces for maximum effect across every side. Install spring according to your bed type (spring inside bed holder bottom); do not make an error with parts otherwise there'll probably always exist wobble somewhere along its path due entirely incorrect design choice leading straight away toward inevitable failure eventually - especially considering limitations often dictate final outcomes when it gets close home...
