Silvestr - Linear Delta 3D Printer

thingiverse

Don't use this design for delta mechanics. Even though these clamps are quite strong, their feelers end up being too weak and allow tiny movements of balls along the clamps. When assembled, the whole mechanics isn't tough enough; it gets worse when parts move around. I still like the idea of making compact mechanics, so I'll try to redesign clamps to get rid of this soft backlash behavior. Here's another version of delta mechanics using 16mm ball joints. It's compact but stronger and more solid than the previous one. Again, it's compatible with Rostock (platform offset - 33 mm; carriage offset - 22 mm). Carriages are designed to be used with lm8uu bearings. Note that the platform's top and bottom sides are different. Parts' sources are published on Onshape. I've upgraded my printer with the parts made of PLA and am currently testing it. Preliminary results are quite promising. Print Settings Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 62% Notes: extrusion width: 0.4 mm; perimeters: 5; no gap fill; Post-Printing I sanded the clamps' feelers ends to make them round again.
