Work Sharp Precision Adjust PSA Lapping Film Adapter

thingiverse

This is an accessory for the Work Sharp Precision Adjust knife sharpening system so you can use PSA lapping films to get a mirror finish on your knives. This would replace the normal 3 sided grind stone and you adhere your lapping films, or any other preferred sharpening media to the plates. These are the lapping films that I use as they are the same length as the plates so you only need to cut them once: https://www.amazon.com/3M-TM-Microfinishing-Sharpening-Aluminum/dp/B07TDMS1H8/ref=sr_1_2?dchild=1&keywords=psa+lapping+film&qid=1631742872&sr=8-2 For each sharpener body, print 3 film plates and adhere them to the body with super glue. I find that the side that was on the print bed is smoother so make sure that side faces out when gluing them in place. Printing: - Sharpener Body: Align the body of the sharpener vertically, 20% infill seemed plenty sturdy. I printed with and without a raft and had no problems with it coming off the print bed. - Plates: Print these flat on the bed and use 100% infill. I had an issue where a corner would sometimes lift off the bed during printing but it was hit and miss. - Word of caution, I designed these to the dimensions that worked best with my printer's tolerances. You may need to either scale the parts up or down maybe 1% depending on how good your prints come out. Edit: Rearranged objects in the stl files so they are oriented correctly.
