Razor Guillotine

thingiverse

I required a reliable means of cutting heat shrink tube into consistently short lengths without posing a hazard due to exposed blades. Given this necessity, I had to find a way to implement it securely. A key concern was safety: any cut length exceeding the capacity posed a threat to user well-being; I addressed this by creating an obstacle-free workspace. For effective heat shrink cutting and efficiency's sake, optimal spacing should never be overlooked, nor can human factors' impact be dismissed altogether. I resolved to integrate K&S stock #508 (5/32 inch) music wire – easily obtained at any reputable hobby store – to utilize as guide rods, along with 3 lightweight springs, to produce smooth cuts. The razor blade needs extreme care during assembly to prevent unwanted mishaps. Furthermore, please bear in mind you have assumed the risk upon printing this design and should use caution accordingly when executing operations. An enhanced model featuring an extended cutting capacity of fifty mm is provided, ensuring added safety through a reduced hazard quotient due to increased distance between components and materials being processed within. Upon testing these upgrades for effectiveness and operational usability without complications: Updated models show clear results as evidenced by accurate 3d printed cuts. Instructions: Ensure precise layer adherence. Using an average Fused Filament Fabrication print setting with .2mm infill can result in perfectly adequate cut dimensions if executed properly. Please take notice of a minor adjustment that must be done; guide rod holes demand attention to clearances that should not exceed a maximum tolerance for snug fitting performance. Also ensure you execute correct push and secure all 100% end stop fittings along with proper engagement on tap the threads at the same location with 3 mm threads without damaging. Insert Teflon to help smoothen cutting performance after installing necessary guides: dry lubrication is recommended; also a simple yet crucial tip for maintaining consistent and optimal performance in any Fused Deposition Modeling or FDM device or technology application. All designs, materials, manufacturing techniques used have all undergone rigorous testing to guarantee reliable accuracy of output that is most satisfactory to even the very most critical and demanding operators who wish precision down to almost atomic scales
