Cellestron NexStar 8SE Collimation Screw Knob

I didn't like the Philips head screws that came with my Celestron NexStar 8SE from ~2023 because I was concerned that the screwdriver might slip and scratch the primary, so I decided to take them out and see what the length, thread and diameter are. They are 8mm long M3 screws with 0.5mm pitch. I replaced them with 8mm hex screws from Amazon set https://www.amazon.com/dp/B0FJDY5PFN?ref=ppx_yo2ov_dt_b_fed_asin_title, but then I didn't like having to use an Allen wrench to adjust them. So I found a M3 thumb screw cap at https://makerworld.com/en/models/74557-knurled-handle-m3-to-m8-socket-head-cap-screw?from=search#profileId-78947, but it was too short for my taste. I modified it in TinkerCad, used PETG with 100% infill and then glued them to 8mm long M3 bolts, using super glue. Now I can adjust collimation using only my hands. This is a nice alternative to a way overpriced solution that most people use to replace their collimation screws. This is very simple design, but I hope somebody finds it useful.
