{"product_id":"1140_untitled","title":"Steam Traction Engine","description":"Bring early 1900s industrial character to your layout or display with this steam traction engine model, delivered as a single 1:87 (HO) master STL. The model preserves the defining features of a road locomotive: a horizontal riveted boiler with visible seam rivets, a vertical smokestack forward of the boiler, a large spoked rear drive wheel with rim-mounted traction cleats, a smaller spoked steering wheel at the front, exposed side gearing and a canopy-covered operator platform. What’s included: one watertight 1:87 STL with named sub-meshes for wheels, boiler, gears and canopy supports. Printing tips: orient the model on its side or on the frame rails to reduce bridging; use 0.12–0.20 mm layer height for FDM; resin prints yield the cleanest rivet and spoke detail. The listing includes a short guide to scale conversion (how to resize the 1:87 file for 1:72, 1:48 or 1:160). Suitable uses: HO model railroads, period dioramas, museum display models and tabletop scenery. Note: smallest internal fittings were simplified where the photograph lacked clarity.\u003cp\u003e\u003cstrong\u003eAvailable railroad scales:\u003c\/strong\u003e Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)\u003c\/p\u003e\u003cp\u003eReady to print digital download in one piece with no assembly needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT: You are purchasing the file in the scale selected below.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMiniature Reality\u003c\/strong\u003e Makes practical, print-ready scenery and vehicles so you can economically fill out the background of your layout, diorama, or tabletop without paying centerpiece prices for everything \u003cem\u003e( We want your miniature worlds to feel real and full of life - with more variety, more detail in every scene, and prices that won't hold you back.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMiniature Reality Personal-Use License (No AI \/ No Resale)\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAllowed: personal printing for your own layouts, dioramas, tabletop games, and personal display.\u003c\/li\u003e\n\u003cli\u003eNot allowed: sharing or distributing the digital files (free or paid), re-uploading to any site, bundling, remix resale, or selling\/redistributing printed outputs.\u003c\/li\u003e\n\u003cli\u003eNot allowed: using the files (or derivatives) to train, fine-tune, test, or feed any AI\/ML system (including dataset creation).\u003c\/li\u003e\n\u003cli\u003eNot allowed: commercial use of any kind without a separate written commercial license from Miniature Reality.\u003c\/li\u003e\n\u003cli\u003eEnforcement note: digital files may include purchaser-linked identifiers \/ forensic watermarking to help investigate unauthorized distribution.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Miniature Reality","offers":[{"title":"Z (1:220)","offer_id":43912837562455,"sku":"mr_0dfb74_8cf93a55-220","price":2.99,"currency_code":"USD","in_stock":true},{"title":"N (1:160)","offer_id":43912837595223,"sku":"mr_0dfb74_8cf93a55-160","price":2.99,"currency_code":"USD","in_stock":true},{"title":"HO (1:87.1)","offer_id":43912837627991,"sku":"mr_0dfb74_8cf93a55-87","price":2.99,"currency_code":"USD","in_stock":true},{"title":"S (1:64)","offer_id":43912837660759,"sku":"mr_0dfb74_8cf93a55-64","price":2.99,"currency_code":"USD","in_stock":true},{"title":"O (1:48)","offer_id":43912837693527,"sku":"mr_0dfb74_8cf93a55-48","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:24","offer_id":43912837726295,"sku":"mr_0dfb74_8cf93a55-24","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:32","offer_id":43912837759063,"sku":"mr_0dfb74_8cf93a55-32","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:43","offer_id":43912837791831,"sku":"mr_0dfb74_8cf93a55-43","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:72","offer_id":43912837824599,"sku":"mr_0dfb74_8cf93a55-72","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:100","offer_id":43912837857367,"sku":"mr_0dfb74_8cf93a55-100","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:120","offer_id":43912837890135,"sku":"mr_0dfb74_8cf93a55-120","price":2.99,"currency_code":"USD","in_stock":true},{"title":"1:144","offer_id":43912837922903,"sku":"mr_0dfb74_8cf93a55-144","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2078\/1911\/files\/1140_Untitled_camera001.png?v=1780249461","url":"https:\/\/miniaturereality.com\/products\/1140_untitled","provider":"Miniature Reality","version":"1.0","type":"link"}
