M4 Hop-up Unit for an Airsoft Gun. Should work with any TM Compatible Airsoft Gun. Been looking for an 3D Printable Hop-up and None where available, So i ported an Model Created By an user on GrabCad user to STL files. Some sanding / cleanup may be required to get the parts to fit well. I also found that Printing the Adjustment Wheel with an 101-105 scale helps to get it fit better. All Credit for the Model Files goes to Szilagyi Laszlo Over at GrabCad. I only Ported this to STL files So it can Be Printed. I included the Model for the 0-ring of anyone wants to Try a Flexible Filament. or you can buy an O-ring from an hardware Store I also included the Peg for the Hopup Arm. I used an Piece of 1.75mm filament as it fit perfectly. Print Settings Printer: Prusa I3 mk2 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: .1mm or lower Infill: 20% at least Notes: Build plate only Support may help Only Use Bed Plate Support to Prevent Blockage of Chamber, and Easy clean up Printing the parts at 1.06 and the Adjustment Wheel at 1.08 Scale on Cura may help if your barrel and Bucking fit to snug.
