108 Well 16mm Tube Rack

thingiverse

UPDATE: Well, I feel stupid. I forgot to include a bottom well shelf thing so the tubes don't just plop down on the floor. Added. My lab no longer needs more 108-well racks, but I AM kinda sick of using the Heathrow Scientific wire racks, as the weld joints and wires themselves are pretty flimsy. So I designed this just because. These files should print without supports, but there is an alternate version of the Knobs that has a 0.6mm thick "fake support" ring around the inside just in case your slicer hates you. It shouldn't be too tough to break off/clean up, especially once you shove the screws/nuts inside. Please print: *1xLeft side *1xRight side *6xKnob for M3 (Optional) *3xWells (2x if you have short tubes. You can then cut the top ~25mm off each of the Right and Left Sides in your slicer) If you have a CNC router, you can use the CNC version of Wells.STL to save a ton of time. Wells.STL requires a 280*210mm or larger bed to print. I wanted extra clearance for tube caps, so it's a bit wider than it needs to be. I might figure out a version that snap fits into itself in two parts so it can be printed on an Ender 3 size build plate. Please have 6-12 M3 nuts and 6 M3 screws ready. The screw length doesn't really matter, but the sweet spot should be 12-20mm, depending on whether you printed the knobs. I haven't printed it yet as I can't figure out how to get the Wells.stl file to print in under 3 hours, and I designed this item to require three of them. The rigidity of the Wells part should be near-zero when empty, but that's why you put tubes in. LOL. If it's filled with tubes it should be fairly rigid. Let me know if it's too flimsy, please. I personally am just going to CNC cut HDPE or aluminum for the Wells part.
