The unofficial drybox heater upgrade https://www.printables.com/model/883817-unoriginal-prusa-heated-drybox requires different G1 and G2 beams than the original drybox https://www.printables.com/model/551828-unoriginal-prusa-drybox.
Would you like to only have to print 1 set? With this adapter, you can use the normal humidity gauge and hold the heater's G1 and G2 beams together. Now, you don't have to complete the heater assembly before the drybox can be completed. Or, you can change your mind about installing the heater and not have to reprint any beams.
