Summary

A large passive cloth enclosure for FDM 3D printers that traps the printer’s own heat instead of adding any of its own. Check your ABS temperatures before you buy: there is no heater or sensor, and no independent test has measured this exact enclosure.

Strengths

  • Passive by design: no electronics, no consumables, no electricity; the ownership cost is the purchase price alone.
  • One owner reports the chamber “stays very constant while printing in a cold garage”.
  • Four owners on Longer’s own site praise assembly, shipping and customer service.
  • The frame is removable and the cover folds, so the enclosure packs away.

Weaknesses

  • “Constant temperature” is unquantified: no chamber temperature rise, warm-up time or test data is published for this enclosure.
  • No heater, fan, sensor, LED or filtration, while competing tents at higher prices add those.
  • One owner reports the filament inlet sits on a side with no opening, forcing the printer to be rotated to load filament.
  • No independent test and no dedicated owner thread exist for this exact enclosure.
  • Flame retardancy is claimed “double-sided” with no test standard or certificate named.
  • The warranty table does not itemize cloth enclosures, and the extended-warranty rule excludes accessories.

What “constant temperature” means here

All thermal benefit comes from trapping the heat the printer already produces. Category-level testing of passive cloth tents — not this product — puts chamber air around 35–50 °C, which helps PETG and often ABS in a mild room. Users report needing roughly 50–65 °C chamber air for ABS, and general guidance puts a good ABS enclosure temperature near 60 °C while warning that 65 °C stresses printed parts and printer electronics. A passive tent in a cold room may not get there. If you print ABS in a cold garage, bring your own thermometer and verify the chamber before committing.

What owners report

Owner evidence for this exact enclosure is thin: four reviews on Longer’s own site, which is first-party and low-evidence. One owner says the temperature “stays very constant while printing in a cold garage”; another says it “went together great”; a third praises “fastest shipping and amazing customer service”; a fourth, from 2024, says it was quick to assemble and “delivers what it promises”. That is a single report, not a measured failure rate.

Is it worth it?

Longer lists the enclosure at $79.99 on sale against $109.99 regular, and Newegg lists it at $99.99 (a page dated 2024-06-26, so that figure may be stale). At the sale price the size-to-price ratio is hard to beat for a Longer or similar mid-size FDM printer. At $110 or more, compare tents that add LED lighting, ventilation or filtration. If you print ABS in a cold room, verify the chamber temperature with your own sensor first.

Which model this is

This page covers the Longer 3D Printer Constant Temperature Enclosure, ASIN B0BBV596VH. Longer publishes no separate model number for it. Do not merge it with the smaller Creality, VEVOR, SUNLU or YOOPAI cloth tents or with rigid-panel enclosures; those are different products.
