An affordable, open, self-hostable shared-3D-printer job queue for makerspaces/universities/libraries with SSO and per-user-private jobs - the FOSS tools are single-brand and the printer-agnostic option is enterprise-sales-gated

saas real project •• multiple requests

Institutions running shared 3D-printer fleets (universities, makerspaces, libraries) want a submit, admin-review, print, and per-user status workflow where students cannot see each other's files, with SSO against existing campus accounts and self-hosting for cost and privacy. They are stuck on email-based workflows because the capable FOSS tools are single-printer or single-brand and the mature printer-agnostic platform (3DPrinterOS) keeps the institutional features they need (SSO, on-prem, per-user-private fleet queues) behind quote-only Education/Enterprise tiers, with only a single-user public plan beneath them. The value is an affordable, brand-agnostic, self-hosted queue that these budget-holding institutions can actually deploy.

builder note

Don't try to out-feature 3DPrinterOS - it already has on-prem and SSO; win on being open, cheap, and genuinely printer-agnostic (OctoPrint/Klipper + Bambu + Prusa) with dead-simple SSO, because the buyers are cash-strapped labs and libraries currently choosing email over a quote-only enterprise tool.

landscape (4 existing solutions)

For institutions the realistic choice is a capable but enterprise-sales-gated SaaS (3DPrinterOS) or DIY/abandoned/single-brand FOSS, so there is no affordable, open, printer-agnostic, self-hosted queue with SSO and per-user privacy - which is why universities keep building bespoke submission portals or running everything over email.

3DPrinterOS Verified on their site: the dominant printer-agnostic education/library platform DOES offer private-cloud (on-prem) deployment, SSO, print queues, and per-team access controls - but those institutional capabilities live only in its quote-only Education and Enterprise tiers (custom pricing, demo-gated). The one public self-serve plan, Premium at $19/month for 2 printers and a single user (14-day free trial), is single-user remote management and cannot run a shared, per-user-private institutional fleet - leaving the needed setup out of reach for small makerspaces, libraries, and cost/privacy-driven self-hosters.

bambuddy Capable self-hosted FOSS fleet manager, but Bambu-Lab-only, and per-user-private queues plus SSO are still in 'Supporter voting', not yet built.

OctoPrint / Obico One-printer-per-instance and single-user oriented; no native multi-user submit/review queue with per-user privacy across a fleet of printers.

BotQueue A FOSS multi-printer queue in concept, but RepRap-era and effectively unmaintained.
