Duplicator 6 Glass Bed Clamps

thingiverse

UPDATE 7/11/2018: * I added files for a small thumb wheel for the tensioning bolts, which are heat pressed into plastic. We'll see how long they last, as they seem strong enough because you don't need to tighten these too much to secure the glass. I printed them in PLA because they don't directly touch hot metal. I designed these glass bed clips to securely hold a 4mm thick glass bed with cut off corners. The front pair are adjustable, while the back pair are static. You slide the glass bed against the back clips and then secure it with the front ones. This is the one I have: https://www.amazon.com/gp/product/B07B2YLWF9 I know many beds are 3mm thick, and the file could be redesigned to work for that easily, but since I don't have a 3mm bed, it's up to someone else to remix it. These have proven to be a bit fiddly, but hold the bed very securely. They were very challenging to print, especially because of how ABS shrinks. It is essential that parts or screws are flush with the top of the clamp. You need clearance for the fan shroud or it will catch on the clamps and either rip off the clamp, or do some other damage. Use an extra nut and some washers to prevent the bolts from going too far (or cut them with a Dremel). See pictures for an example. Here is the link to the Fusion 360 files; I'll make tweaks as I gain experience using this part: https://a360.co/2NFrR6E I am not yet happy with all the tolerances, as the screw holes and nut recesses are too tight when printing in ABS. Additional Parts/Hardware: 4x M3 8mm bolts - these attach the clamps to the platform, replacing the existing heater pcb bolts 10x M3 14mm bolts (or 16mm bolts with extra nuts and washers for spacers) 10x M3 nuts 12x M3 washers
