PVC Bow Riser

thingiverse

My dad is working on a PVC bow, so I thought I'd make him a bow riser. I used Ian Sayer's bow grip design from GrabCAD and modified it to be 10.5 inches tall, which fits my delta printer and works with 1 inch PVC tubing. I also added two slots for M3 bolts to add more hardware to the bow in the future. I printed the riser using Simplify3D with the following settings: Delta printer No rafts Yes supports Resolution of 0.3 mm Custom infill, see notes Notes: For this print, I used a resolution of 0.3 mm and set the infill to 50% triangular in the middle section (39-224 mm). I made the outer layers solid from 0-39 mm and 224 mm to the end. Post-processing involved using a pen torch to strengthen the print by melting the outside layers together and fusing them completely. This process took about 45 minutes, but it was worth it – the part is now very strong and watertight. Just be careful not to burn the PLA or deform the final product. I used SolidWorks to import the STP file as a solid object and modify it to my needs. I based my design on Ian Sayer's bow grip STP file from GrabCAD.
