Crank Handle for Ikea LJUSA torch

prusaprinters

<p>Ikea Ljusa [yoo:sa], which means bright in swedish (adjective of bright) has an annoying crank handle without rotating crank knob. The handle is just one peace of molded plastic!&nbsp;</p><p>Ljusa is a flashlight with hand crank generator (step motor) and with super capacitors as a storage of energy.&nbsp;</p><p>When you try to crank this torch light you immediately realize how uncomfortable it is due to lack of handle free rotating knob.&nbsp;</p><p>How to take apart your torch, can be find by help of Google or Youtube.&nbsp;</p><p>To get the crank handle assembled, you need to print three different details. The Crank Knob does not need any support material, but other two need it.&nbsp;</p><p>After details are printed, you need to remove and clean all support material. Use a magnifying glass, sharp scalpel and pliers. Assemble all three details as my picutres show. You may secure crank shaft in place with a few drops of quick adhesive (<i>cyanoacrylate adhesive</i>), but it is not necessary. The crank knob has to rotate freely on crank shaft as it does on my prints.&nbsp;</p><p>Now assemble the complete torch together with removed cover, adding new crank handle.&nbsp;</p><p>You will feel how easy it is to wind the torch now.&nbsp;</p><p>&nbsp;</p>
