8/super 8 film winder
Description
This is a simple film rewinder for cleaning/rewinding etc 8 and super 8 film using an R8RS bearing for friction mitigation the shaft should be printed horizontally for the greatest strength and the winder should also be printed in a similar manner so that the winding shaft (which can be driven using a drill) is printed in the strongest orientation. printed in PLA at 25% infill which seems to work. some parts especially the ring which is being used to position the shaft on the bearing are very tight so some play to make the tolerances work may be necessary on your printer. this is similar to/a reverse engineering of the 16mm rewinder by Zlp: https://www.thingiverse.com/thing:4638847 this uses bearings such as shown here: https://www.amazon.com/R8-2RS-Groove-Bearings-Miniature-Pre-Lubricated/dp/B07KTM61X9/ref=sr_1_3?dib=eyJ2IjoiMSJ9.meELqtuZA50X-_zLJBD1hzQ2F_GH50ezMafAT1PJKYrqYfXOrQunrvH_kE-ZTrxAEUEKR7lqYbGbtkCv3DMV291rdHhT3NqiXgUguy4LeVWSapTaZgRYaXV5M5aoRA4ISZSqO7UEaYlM2z9jGBisFebdxnCFrzvW7O7JGex_BrxDrYUXkQmrYP4lMD_XH1I4Gl53u5eNzONCwG1lGugwN9aMnZp0UB3jS-_HsU2eazk.jdgnTBMffX-bhmKNoXEt3VeVWB5pZVeu4_UaB_56c8A&dib_tag=se&keywords=r8rs+bearing&qid=1725498269&sr=8-3
