Sequential mod for Moza HGP shifter

UPDATE 11.12.2025 Updated TPU “spring” added to design. I printed it from Extrudr Flex Semisoft Tpu, 85A Hardness. Works like a dream. 0.28 layer height, 15% gyroid infill. I have had several O-rings snap using this mod for a while, and I think TPU spring solved the issue for me. My take on mod Moza's HGP H-pattern shifter to be used as sequential shifter. I wanted to make it as simple as it can be, but look decent and feel solid. Stays securely on its place using magnets. Only few non-printed parts are needed, listed below. Should be easy enough to source. I used superglue to attach extension nuts to top part and magnets to bottom. Hardware needed:- 4 x 10mm x 2mm neodymium magnets- 2 x M6 extension nut, 25mm length- 2 x M6 x 20 bolt- 2 x M6 washers (optional, not necessary)-1 x printed TPU spring If you go for original model without using TPU spring:- 3 x 3,5mm x 30mm (or similar) rubber O-rings- Some foam for added dust-proof and dampening (optional but recommended) No post-proc
