Keep the surface wet to avoid clogging the paper and to reduce heat friction on the plastic. (ALWAYS SAND IN CIRCULAR MOTIONS) https://freight.cargo.site/t/original/i/Q2917824851326159770653269377041/step-1.png Step 1: Start Rough (200–400 grit) Get rid of major layer lines.

(ALWAYS SAND IN CIRCULAR MOTIONS) https://freight.cargo.site/t/original/i/G2917825002939949312472074108945/step-2.png Step 2: Medium Smoothing (600–800 grit) Eliminate the sanding scratches left from Step 1. The surface should start feeling noticeably smoother under your fingers. Keep it wet throughout. https://freight.cargo.site/t/original/i/H2917825099785355699447220092945/step-3.jpg Step 3: Fine Finishing (1200–2000 grit) At this stage you are refining, not removing material. Work slowly and evenly across the whole surface. By 2000 grit the cover should feel almost smooth to the touch. https://freight.cargo.site/t/original/i/B2917825181301517761169728684049/step-4.png Credit: <a href="https://www.3dsourced.com/guides/sanding-pla/" target="_blank">3d Sourced </a> https://freight.cargo.site/t/original/i/L2917828370632887641108945780753/1.png Step 1: Mix the Resin Mix XTC-3D Part A and Part B in a 2:1 ratio by volume. Stir for at least two minutes; undermixing will leave soft or tacky patches after curing. *Optional Primer Apply a light coat of spray primer and let it dry fully. This helps reveal any remaining imperfections and gives the resin a better surface to bond to. https://freight.cargo.site/t/original/i/W2917828414609925512832516833297/2.png Step 2: Apply the First Coat Using your disposable brush, apply a thin even coat over the entire surface. Work quickly as the resin begins to self-level within a few minutes. Thin coats are always better than thick ones — one heavy coat will drip and pool. https://freight.cargo.site/t/original/i/E2917831020968842431328774209553/3.png Step 4: Optional Second Coat Once fully cured, lightly sand with 1500–2000 grit again to knock back any unevenness, then apply a second coat following Steps 5 and 6. This will give you a noticeably glossier and more durable finish EXTRA TIPS: If you want color, paint before applying XTC-3D so the resin seals and protects the paint underneath Wear gloves! The resin is sticky and skin-irritating before it cures Work in a well-ventilated space, the fumes during mixing are strong.

Keep it in a warm room — XTC-3D cures faster and more evenly above 20°C. https://kahlumna.com/t4-measuring 2026-05-15T13:14:39+00:00 always 0.5 https://freight.cargo.site/t/original/i/F2917456019174603326109442326545/Screenshot-2026-05-02-at-14.06.42.png Step 1: Measure Your Pylon Wrap a measuring tape around your pylon to get the circumference, then divide by π (3.14) to get the diameter. This number determines which TPU inner ring is right for your setup. https://freight.cargo.site/t/original/i/X2917876026560270216797005758481/Measure-Circumference-B-2.jpg Step 1: Measure Your Pylon Wrap a measuring tape around your pylon to get the circumference, then divide by π (3.14) to get the diameter.

These rings are what allow the clamp to grip pylons of different sizes. https://freight.cargo.site/t/original/i/Z2917883470762287906360269946897/IMG_6125.JPG Step 3: Print the TPU Ring and Clamp, Print the TPU ring in with TPU filament and the clamp in your material of choice (PETG for a stronger piece, although PLA works fine aswell.) The ring slots into the clamp, creating a secure and customized fit for your specific pylon. Don't see your measurement? Not every size is listed yet.
