Lamp/microphone strong clamp (variants)

prusaprinters

Really strong clamp for lamp, microphone or other purposes.I have used different design tricks to make it stronger than other clamps. I am really surprised how strong it is, with such size. The hole for microphone/lamp have 12 mm diameter + tolerance. You can insert smaller too.The counter screw and nut are 4mm. VariantsThere are Clamps dedicated for 5cm, 4cm, 3cm, and 2cm (or lower) board thickness etc. There is also 3cm clamp big (same screw). Designed for my son microphone. He tortures it mercilessly :) PrintingPrint without supports with PETG (I did not tested other materials). There are speciall infill settings for clamp and the screw.Look at 3mf file for modifiers. Do not rotate models on the plate, as line infill 0 degrees angle is important here for strengthen. Do not modify perimeters, 3 are ok with this infill method. More can make it weaker (counterintuitive). 3mf file contains all variants, so simply delete not needed from the slicer plate.I strongly recommend short screw with fit size clamp. I have included long screw if you need one universal size clamp, but better use better fitted clamp with short screw. MountingDepend of your print quality, as the thread is printed in rotated position, thread can have some pollutants so you must turn the screw few times. It must be printed in this orientation to make clamp strong. But thread tolarance is big, so no problems should occure.Mounting LampScrewCapIt is easy to mount part, simply put into the screw.Mounting the metal nut for 4mm counter screw:To insert it easy, do not try to put it into the nut hole. Easier is putting nut on the bottom and inserting the screw (some longer one) from the top (look at last photo). Then pull the screw with the nut to the top and the nut simply go into the hole. Then change screw to some short one, the best the wing screw (i do not have wing screw so i use normal).This way was easier to me, maybe you have better method.
