MATERIAL NOTES: This product is printed in PETG material which offers superior thermal resistance and increased durability compared to PLA products. PETG has a higher glass transition temperature of 80°C whereas PLA is 60-65°C. For PLA, this is within range of the temperatures that often occur inside a vehicle during summertime so items made from PLA may end up warping in those situations. The same issue can possibly occur from exposure to direct sunlight if the temperature is high enough. PETG has a much higher glass transition temperature however so you are very unlikely to ever experience issues with it warping in addition to it just being stronger in general. PETG products do come at a higher cost than the same product in PLA because PETG takes longer to print and also requires more time to clean up after printing but the result is a very high-quality product. DISCLAIMER: All of my products are printed and tested with the utmost attention to detail. Despite this, I am NOT responsible for any damage incurred to you or your blasters through the use of any of these parts by themselves or in combination with others. It is up to you to keep yourself and your blasters in functioning condition. Some prints may have slight imperfections as is common to all 3D printing (especially for PETG). These slight imperfections will not interfere with mechanical function or integrity/strength. B-STOCK: B-stock items are items that are only defective in appearance and are offered at a discount for this reason. They should function like the normal product unless otherwise specifically noted in the listing. Powered by ExportYourStore.com
